Wouldn't it be possible to implement specific themes for this? If themes could define also menus and their commands, Reaper could come with Simple and Advanced themes, in addition to the color and icon themes we have now... A n00bie (like me) would start with a Simple theme, with the absolute basics, and once that was mastered I could load an Advanced theme and explore that. Of course, deciding what features are Simple and Advanced, resp, is another matter... EDIT: The Wiki, BTW, now includes a Loop Source page,
