Allow maximize/fullscreen of the DeskPad window

[glenmurphy]

MacOS' Spaces is limited by forcing all spaces to the same resolution, so you can't have an easy-to-read consumption spaces and a high-res programming space. DeskPad on its own dedicated space almost solves this, but would be made better by adding fullscreen support to avoid the double-menubar problem; it would also remove the need for manually creating a space for DeskPad ahead of time.

In a similar vain, enabling the standard Mac OS window menu would give the ability to use window tiling functionality and keyboard shortcuts within Sequoia.

Being able to maximise the Deskpad window to full screen would be super useful too. I use this app to create a virtual desktop that I can run in the background, and then use chromecast to send to different displays, e.g. for casting dashboards.
