Feature request: Add command line options to manipulate position of secondary windows

[AAA1exa8]

It would be nice to have command line options to set position and whether the window should be maximized for secondary window.

I'm willing to code it up if this is something the upstream would be interested in. I'm just not sure what the syntax should be.

(My use case is that I'm building a small dual screen handheld and I would like to have one of the DS screens on each of the handhelds screens)

Not an official contributor...
but I forked a version for the purpose of running on Raspberry Pi 4/5 (RPiOS Bookworm) so that I could accomplish some dual screen magic. I can't say that it will work on anything other than the Pi 4 since that is all I have tested in on so far, but it's available on my profile as melonDSpi. You'll need to build from source, but the standard instructions should work.

It automatically launches 2 windows, moves 1 to the 2nd physical screen, and then fullscreens them both. I also added a few "quality of life" things, but that's the biggest customization. Feel free to use the code directly or as inspiration. Also, I recently joined the Discord if you want to have more discussion there. I don't want to clutter the main GitHub repo discussing my fork (unless the devs want that).
