Minimize/expand plugin UIs to/from a bar with a double click

In some projects some plugins are more important than others and you are constantly switching from a very small subset of plugins UI’s to make tweaks (ie. compressor,filter,synth vst). If you could have all of their UI’s open and be able to minimize them to a bar and then expand them back, that would be absolutely wonderful and a huge time saver (now there is no other choice but to move them around constantly, moving to the edge those you don’t want to see and moving the center the ones you want to be visible; and if you make a mistake and close one of them in a project of 30 tracks, good lord it’s a pain to find the button to open it again).
