the vast majority of applications do not work in linux
oh yeah man, what a discovery. Because they where not written for Linux. And they where not written with some kind of OS independent framework like QT. For instance, XnView is a nice photo and image album program, running on Linux as well as on Windows (Mac, I do not know).
I am mostly running Mint Linux on my desktop system. Only when I run RigManager and some very view other programs, I am booting Windows.
I tried to use RigManager within Linux virtualization software (Qemu/boxes), Windows in this box. This works, but due to USB virtualizations, it is kinda slow. So, I would like to see RigManager running native in Linux. But I think, Kemper will not support this because to few users are Linux guys, and because this would only affordable, if RigManager was written with such an OS independant layer framework.
