Well thats up to Lokasenna... and how much will I annoy him
. Yeah its already available on ReaPack (Lokasenna Radial Menu)
important info, this code and features I'm adding / showing here are not in main version,but I hope some of them will be incorporated in main version
btw I think it's better to have setup activated on right hold,so right click will would be free for "back" (return to main menu). So you can single activate on key release and multi activate (for example add markers while playing,record punch in or out,change peaks on fly etc) on left click and if you want to go back to main menu you click in middle or right click
