[Feature Request] Separate tab to new window

Is your feature request related to a problem? Please describe.

Sometimes I have two files open in different tabs of the same window, and would like to have them visible at the same time. This is very common because DrRacket will default to adding a tab to an existing window when opening a new file.

Describe the solution you'd like

The ability to separate a tab to a new window. This could be a keybind, and/or ideally happen when a tab is dragged up/down from the list of tabs (like in Firefox/etc). Also helpful would be an option for DrRacket to open files in their own windows, and the ability to combine windows into one tabbed window.

Describe alternatives you've considered

Currently, if I have a file open in DrRacket and want to open another one in a different window, I first create a new window (whose blank file is then replaced).

Start by reproducing the described workflow: open two files in DrRacket tabs, then create a separate window. Investigate the existing tab and window-management entry points; the issue's possible outcomes include detaching tabs, opening files in separate windows, and combining windows, so completion requires clarifying which behavior is in scope.
