There are currently 5 tabs per song: General, Patterns, Samples, Instruments and Comments.
Maybe its an idea to allow it to become seperate windows, so you can put them on 2 monitors if you have it?
I think its best to just allow to undock one window, and leave the song itself in tact, so it just makes a replica of that tab in a new window?
This way, you can edit the patterns while tweaking in the general tab, and if my other request about plugins has been realised, you can do that too.
