A native Linux version of REAPER would be great. With more serious VST-capable DAW software running on Linux, more professional plugins for that platform might get developed, too. Ardour isn't really usable - even the latest version 4.1 is a pain in the ass, but Bitwig was a pretty good start, and it would be awesome to add a widely accepted traditional DAW like REAPER to the list. Come on guys, I'm sure it can be done. 25 - 30 years ago I would most probably have done the port myself. :)
