Overwrite shell interface
Hello! I'm still fairly new to Linux, and since I'm trying to use the terminal as my primary interface, I've been spending a lot of time working in Bash.
After about a month of daily use, I've noticed a few things that make the experience less comfortable. Features like autocompletion, syntax highlighting, and autosuggestions are easy enough to add with plugins, but there's one feature I haven't been able to find anywhere.
I'd love to have the command prompt stay fixed (sticky) at the bottom of the terminal, similar to the input box in a chat application.
For example, when I scroll up to review previous output, I'd like the prompt to remain visible at the bottom instead of scrolling away with the rest of the terminal. If I start typing while I'm viewing older output, it shouldn't automatically jump back to the latest line. The prompt should stay fixed until I explicitly choose to return to the bottom with ENTER key.
The idea is similar to this Bash workaround:
```
# .bashrc
_prompt() {
tput cup "$LINES" 0
}
PROMPT_COMMAND="_prompt; $PROMPT_COMMAND"
```
This kind of interface would make it much easier to review previous output while continuing to type new commands, much like how chat interfaces work.
Is it possible to achieve something like this in Bash?
How to set Window Background via CSS?
How to set Window background Vivaldi via CSS?
I want to set the image on "window background" dynamically via scripting, And the way that came to mind was to rely on CSS custom file.
So, does anyone know how to change the Vivaldi window background using CSS? Not directly in the theme settings.
Or is there another way besides using CSS? Via preferences? but how. Just suggest it here! Thanks..
Vivaldi v.7.9.3980.182
