Subject: [PATCH] chore: allow dragging window from titlebar when maximized
 (#178)

This better matches titlebar behavior of Windows and KDE, and probably a lot more other environments, it also allows for easier unmaximizing because the current titlebar has no dedicated maximize/restore button.

Note: This is somewhat problematic on Windows, thus we only apply the change to other platforms for now.
