When I launch Premiere, then switch to another app to keep working, Premiere’s Home window opens and covers my entire screen and is floating over all my other apps and windows, preventing me from finishing whatever I was doing.

The Home window should:
1) Never float over all apps. On macOS, the Home window uses the “small window titlebar”/“palette window” style with thin titlebars. In other apps, these windows automatically hide when the parent app is no longer frontmost. The Home window ignores this macOS convention.

2) Does not need to fill my entire screen. Yes, I want Premiere's standard window to fill the screen when editing, but not the Home window which could be a fraction of the size and still be perfectly usable.
