The idea is simple. When we draw the theme, we should every time:
1. Save rtconfig
2. Move it to ReaperThemeZip and save archive.
3. Open theme in Reaper.
It would be so much useful if we have a possibility to open rtconfig of current theme (via action, for example) in IDE, like script, and of course save/apply it to current theme via Ctrl+S also like ReaScript to preview changes.
Also, as an option could be nice to have all used images used in current theme in the right column (where variables now) with OS context menu, for directly editing every element in external application.
