Make closing settings easier

As I am new to Joplin I am often configuring the Joplin desktop App (Win).

But I think it is not user-friendly to move the mouse all the way down to the left bottom of the Joplin windows to close the settings.

Therefore I suggest to improvements.

  1. Use ESC to close the settings/go back to the main menu.
  2. (optionally) move the "Back" button to the top where most of the action is happening. :wink:
    But I understand this would be a bigger design change.

This would be consistent with another feature request.

I just realized "Back" does not save changes.

So I would like add the feature request to ask "Would you like to save your changes?" after pressing Esc.
