I struggled today with only 8/20 🫣

I started to put together a polygon editor for some simple merging that I needed to do for work and got a bit carried away. I turned the app into a user-friendly, but powerful polygon editor.

I would appreciate if anyone would take a look and give some feedback. It’s currently hosted on GitHub. Here's the link: https://giswatidid.github.io/polygoneditor/

Feedback on usability, unexpected behaviour or useful missing features would be appreciated.
