I typically find myself prototyping in the main window, and then once I generally have a good sense of how the UI is going to behave find myself creating Containers. The process of trying to move, cut, paste, etc. all the controls (and migrate the code referencing those controls) from the Window to the Container is a royal PITA.
It would be fantastic if there was a way to just select a group of controls and select “Refactor into new Container…” or similar. There would still definitely need to be some fixes performed afterwards, but having the UI migrated for me and obvious code updates done automatically would be a heaven-send.
