I'd be so happy if it had real-time plugin support.
fyp. That's the real issue, it won't pass data through the plug out to the monitor routing. It's process or bust, and the "preview" function blows. It's one of the few modern editors that does that so I abandoned ship a couple years ago for that reason, I just use it to track on sector boundaries anymore.
I downloaded Reaper awhile back, and the features look great, but it also looked way too complicated for me. I think the learning curve would involve more time than I have available to learn it, even though I think I would produce better recordings with it.
A solid weekend with Reaper is about all it takes to learn it. Audacity works great for just tracking and amplification. For everything else, use a different editor as plugin support is underwhelming in Audacity.
