Simple Date/Time stamp plugin

***Edited to add: I have updated the plugin to add requested features, link is below in the comments.

This is a simple date and time stamp plugin that was requested.

Features

  • Three stamp types: Date, Time, or Date + Time
  • Four date formats: Numeric (4/26/2026), Medium (Apr 26, 2026), Long (April 26, 2026), ISO (2026-04-26)
  • Optional day name: e.g. Sunday, April 26, 2026
  • 12 or 24-hour time
  • Optional seconds in time stamps
  • Font size: S / M / L / XL
  • Bold and italic styles
  • Alignment: left, center, or right
  • Insertion position: bottom of page (with alignment) or fixed top-right corner
  • Stamp is inserted as an editable text element

Installation

  1. Download DateTimeStamp.snplg from the latest release.
  2. Connect your Supernote to your computer using the Supernote Partner app or Browse & Access.
  3. Copy DateTimeStamp.snplg into the MyStyle folder on your device.
  4. On your Supernote, open a note, tap the plugin icon in the toolbar, go to Manage Plugins, tap Add Plugin, and select DateTimeStamp.

Usage

  1. Open a note and tap the clock icon in the toolbar.
  2. Set your preferences in the panel:
    • Toggles: Include day name, 24-hour time, Include seconds
    • Date format: Num / Med / Long / ISO
    • Position: Bottom (respects alignment) or Top Right (always upper-right corner)
    • Size: S / M / L / XL
    • Style: Bold (B), Italic (I)
    • Align: ← / ↔ / → (applies when Position is Bottom)
  3. Tap Date, Time, or Date + Time to insert the stamp.

The stamp lands at the chosen position as a text element. You can lasso and move it from there.

Calculator and keyworder plugin updates.

Updates to both plugins for new dev updates and some additional changes.

⏺ Calculator Plugin (v2.2.0-beta)

https://github.com/taoist22/sn-calc/releases/tag/v2.2.0-beta

- Manta (A5X2) support — the UI now automatically scales up for the larger screen, so it no longer looks tiny

- Renamed from "SnCalcPro" to "Calculator" in the toolbar

- Fixed a Manta-only bug where inserting a result would duplicate the text at the bottom of the page

- Calculator now clears on reopen — no more leftover formula from your last session

- After inserting a result, the text stays selected so you can immediately move it anywhere on the page without needing to re-lasso it

---

Keyworder Plugin (v1.1.0-beta)

https://github.com/taoist22/sn-keyworder/releases/tag/v1.1.0-beta

- Keywords are now managed entirely inside the plugin — tap Manage to add, delete, or pin keywords directly on your device

- No more web tool, no more keywords.json file, no more USB/WebDAV file transfers

- Your keyword list persists automatically across restarts

- After inserting a keyword, the text stays selected so you can immediately move it to the right spot on the page

- Empty state now prompts you to tap Manage rather than pointing to the old web tool

Updates to SnCalc - calculator plugin

Iʻve made some changes, fixed issues and added a new Conversion Calculator mode.

https://reddit.com/link/1t8occc/video/g937ycr0p60h1/player

Modes

Standard

A 5-column algebraic calculator for everyday arithmetic. Supports parentheses, percentage, and standard operator precedence.

Conversion

Unit conversion across 12 categories: Area, Data, Energy, Force, Length, Power, Pressure, Speed, Temperature, Time, Volume, and Weight.

Tap the category label to switch categories. Tap either unit label to open a selector grid. Both the From and To fields accept direct input — editing either field recalculates the other automatically.

Financial (RPN)

An RPN financial calculator modeled on HP 12C conventions.

  • TVM: Solve for any of n, i, PV, PMT, or FV by entering four known values and tapping the unknown
  • Amortization: Enter the number of periods in X, press AMORT to compute principal, interest, and remaining balance
  • Cash Flows / NPV / IRR: Use g + PV for CFo, g + PMT for CFj, f + PV for NPV, f + PMT for IRR
  • f + [0-9]: Set decimal display precision

Scientific

A 7-column algebraic calculator.

  • Trigonometry: sin, cos, tan and inverses asin, acos, atan
  • Hyperbolic trigonometry: sinh, cosh, tanh
  • Logarithms: ln, log (base 10), log2
  • Exponentials: e^x, 10^x, x^y
  • Powers and roots: x², x³, square root, cube root, y-th root
  • Other: factorial, mod (infix operator), 1/x, absolute value, random
  • Constants: pi, e
  • Memory: MC, MR, M-, M+
  • DEG/RAD toggle; scientific notation entry via EE
  • Implicit multiplication is supported: 2pi, 3sin(30), and 4(2+1) are all valid expressions

Bottom Bar Controls

Present in all modes:

  • Hist navigation (back/forward): Browse previously evaluated expressions (Standard and Scientific)
  • Decimal places (- / +): Adjust the number of decimal places shown, from 0 to 8
  • ,000: Toggle thousands separator on or off
  • Result Only / Full Record: Controls what is stamped into the note
  • Insert: Stamps the current result into the note page at the cursor position

Stamp Modes

Result Only stamps the numeric result, or the conversion pair in Conversion mode.

Full Record stamps:

  • Standard / Scientific: the full expression and result
  • Financial TVM: all register values (n, i, PV, PMT, FV)
  • Financial IRR / NPV: the full cash flow schedule and result
  • Financial Amortization: periods, principal, interest, and remaining balance
  • Conversion: category name, from value and unit, to value and unit

Smart placement detects the lowest existing element on the page and inserts below it.

Installation

  1. Download SnCalc.snplg from the latest release.

​

https://github.com/taoist22/sn-calc/releases/tag/v2.1.0-beta
  1. Connect your Supernote to your computer.
  2. Copy SnCalc.snplg into the MyStyle folder on your device.
  3. On your Supernote, go to Toolbar Plugins icon > Manage Plugins > Add Plugin and select SnCalc.snplg.
  4. Open a note, tap the plugin icon in the toolbar, and select SnCalc Pro.

Usage Notes

  • This is a beta release. Verify critical results independently.
  • Financial mode uses RPN (Reverse Polish Notation). Values are pushed onto a 4-register stack (X, Y, Z, T).
  • The DEG/RAD indicator appears in the top-left of the Scientific display.
  • The memory indicator (M) appears in the display when the memory register holds a non-zero value.

SnCalc update, now SnCalcPro

https://reddit.com/link/1t4xlp6/video/4x215thpxezg1/player

Update to the Calculator plugin:
Added Financial calculator and Scientific calculator modes

These new function have been *lightly* tested. Please let me know if you have issues or suggestions!

Three Modes

  • Standard: A familiar algebraic calculator for quick daily tasks, featuring an ergonomic 5-column layout with percentage support.
  • Financial (HP 12C Logic): A full-featured RPN financial engine. Calculate TVM (Time Value of Money), Amortization (Principal/Interest breakdown), IRR (Internal Rate of Return), and NPV (Net Present Value).
  • Scientific: A dense 7-column algebraic grid featuring over 50 functions, including hyperbolic trigonometry, logarithms (ln, log10, log2), powers, roots (including custom root solvers), and scientific notation.

Smart Audit Trails

  • "Full Record" Stamps: Beyond just results, SnCalc Pro can stamp detailed reports into your notes.
    • Amortization: Stamps a formatted block showing periods, principal paid, interest paid, and remaining balance.
    • Cash Flows: Stamps your entire investment schedule (CF0, CFj, Nj) alongside the IRR/NPV results.
    • Scientific: Stamps the full algebraic expression and the result.
  • Smart Placement: Automatically detects the lowest element on your page and places the stamp below your handwriting, ensuring no overlaps.

High-Precision Engine

  • Deterministic Math: Uses a custom recursive descent parser for algebraic expressions and the Newton-Raphson method for financial roots.
