RFE: UI customization

[BrianHanke]

Hi all, just a quick follow-up to the meeting this morning. I think these are some of the things that would be nice to see in Open RV, UI-wise:

1. Skin/theme chooser in-app, with user-submitted themes available for download.
2. Theme designer GUI for choosing colors, fonts.
3. Sample stylesheet with annotations explaining what everything does.
4. New icons from flaticon.com or elsewhere.
5. The Annotation icons are not hardcoded, but the main window ones are. Change that so it's possible to swap icons without doing a full recompile?

Thanks!
