Ability to pop-out BLACS tabs into their own windows (so that BLACS can span multiple monitors)
Shrink the padding around controls (when I first designed the Qt widgets, I didn't know as much as I do now about layout margins and spacings)
Ability to graphically (via settings panel) alter the distribution of notebooks (e.g. something other than the 2x2 grid we have now)
Ability to launch the tab in a secondary instance of BLACS that is runs on another PC
Virtual devices - A mashup of controls from various tabs. For example you could have a "MOT" device tab with all the IO controls relevant to that, etc. The framework for this actually already exists within BLACS, it's just never been documented or actually used to make a virtual device tab.

We don't know how to describe this, but we have so many blacs tabs that they are a mess to manage. A better organizational principle is desired.
