Perhaps that at some point we will have a docking zone at the bottom where we could dock what we want ?
Reaper does this actually very well (sorry…).
You can have the Media Explorer, the Plugins Explorer, the Mixer, a Navigator, the Routing Matrix, and all the plugins that you want to be there, all accessible with tabs.
All can be docked / float easily like in Acid / Vegas.
Very simple and very useful !
But I suppose that it would need a completely different approach of the windows handling.
