This has been just a minor annoyence for me, I have noticed that doubble clicking a dsp effect that is already open but minimized will not cause it to pop back up, in my mind, clicking an effect in the dsp should make it appear, minimized or not... Just a thought.
If you dont understand what I am talking about, go into the dsp, open up the configuraiton for one of your effects and then minimize it, THEN try and open up the configuration again, nothing will appear. I think that it would be nice if it would appear.
