Reaper's undo history shows parameter changes now, thanks!
I notice that some parameters like steepness of detector, while they do show up in the undo history, have a minor display issue. If I set that parameter to "1" for instance, then change it to "3", then undo (to "1" again), the display still shows "3" until I close and re-open the plugin, or resize it so that it re-draws.
Hit detection for the "grabbing" of nodes works better, thanks!
While on that subject though: in the "settings" dialog, depending on the size of the plugin sometimes it's impossible to select one setting or another. It seems to sometimes select the wrong value (as though it thinks the mouse is clicking 100 pixels to the right, for instance).
Oh and by the way I'm looking forward to LinkEQ!
I don't suppose you plan to include harmonic generation in it as well?
