Why not just have Save and Load buttons in the main window that bring up standard Open/Save dialogs? (And maybe a "Save Defaults" that writes it to the default location. That could be added first, with the extra dialogs added in a later commit.) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8778#note_113179
