Add a GUI directory selector in Copy/Move and Save As dialogs
The Copy/Move dialog displays the destination directory, which by default is set to the directory of the opposite panel as in all orthodox file managers The destination can be changed in the dialog, however, only by manual input. There is no way to select a directory via GUI. There is a similar problem with the Save As dialog in the editor. I suggest to add to these dialogs an option for a GUI directory selector. Out of curiosity, I checked Total Commander on Android, and it has a GUI selector in these dialogs. The best option for a GUI selector might be the Storage Access Framework which is already used in the Home list for the same purpose: directory selection.
