Feature request: Custom CSS for UI
There's no color scheme setting at the moment. Since this is an Electron app, the lowest effort UI customization can be achieved with the ability to add/edit custom CSS.

In the future, I might want to add integration points where one could extend/modify Heynote (not just CSS, but also possible JavaScript). However such feature would have to be thoroughly thought through, and I wouldn't want to just throw in a textbox where one could add some extra CSS, since I believe in committing to keep support for features that are added.
