I'm not sure how this idea will be received. I admit that it's not particularly important, but I think it would be a nice aid to learning. I was inspired by EvilDragon's mockup for the add FX window in
this thread. I had my own idea bouncing around for an improvement to the add FX window. My thought is that there are so many bundled plugins, many being very specific and a pretty obscure in their function, having a description of each would useful to newcomers. Actually, it might be useful to everyone. Something like this (obvously with real, useful descrions of function, input/output, automation, and not my lorem ipsum filler text)
I guess the obvious question is what the description window would show for non-Reaper plugins. I'm not sure. It sorta depends what kind of metadata VSTs generally come packed with.
Another, possibly easier to implement, option would be a hover-over tool tip thing which described the plugin.
