It will be very good to be able to detach from the main window the composer and the terminal special for setups with at least a dual monitor.
Be able to work on all 3 in same time it will solve pretty much a lot of bottlenecks.
Example in my case.
I keep an extra terminal (Termius) use on a small 16” monitor where I run Aider and have cursor both windows (code + composer) into 2 monitors will unlock a lot of work.
Have the terminal from cursor itself it will be amazing.
