Provided Qt5's tab bar supports it, allow dragging tabs back and forth in the right (function panel) tab bar. Allow dragging document tabs in the left (document) tabset.
Again if supported by Qt, allow dragging any function panel out of the main window, becoming an independent window, or drag an independent window back to the tab bar (like a Chrome or Firefox tab). This would be especially useful for when you want two function panels visible at once (e.g. Pngs and Preview).
Not clear if tear-off is feasible for document tabs because so much depends on the "front" document as the target of any function, e.g. Find/Replace. If a document is floating around in its own window, when is it "front" and when not?
