However, with several DAWs, as you scroll through the tracks, the associated plugins for the track you are leaving close, and the plugins for the track you stop on open at their last position. i.e. if I have 2 of 4 plugs open, when I come back to the track, the same 2 plugs will pop open again. Reaper has a container that the plugs float in. Studio One does something similar. Ableton and a few others have the effects rack approach.
