This is a papercut issue - Every time I start FreeTube I always have to manually maximize the window. It's a minor issue but it's quite annoying. It would be great if window size/position were remembered on close.
I'm running Linux (Ubuntu) so I'm not sure if Windows users have the same issue.
I've seen this requested a couple of times so it's definitely something I need to take a look at. I don't know exactly when I'll be able to look at doing this but it's on the radar for the future.
I was about to make a issue until I saw this. I might as well add my niggle to this. FreeTube doesn't remember window position/doesn't listen to window placement on my Manjaro Cinnamon based on Arch.
It always open's top-left even-though I have my system configured to open windows in the center.
I hope you can get around to fixing this!
This has been implemented and will be available in the next release. Closing...
