“In the stable version of Android 15 and previous versions before it, swiping up will get you to the recent app menu, where you can see every app that’s currently open.”

I wouldn’t say that GrapheneOS isn’t ready for daily use just because you have some issues. It’s a mature project with decent support for only a couple of devices and a lot of people use it on a daily basis without issues.
And the base would be Arch Linux ARM, right? So that should see an uptick in development too.
