This is available only for live images.

I am not able to build the live ISO (too few resources) so I cant test this.

@M4rtinK @jkonecny12 can one of you build this for me?

Here is link to your ISO: https://drive.google.com/file/d/1QY_HIyQNDohPYpo7ZKJBB8mqnqk2yFIJ/view?usp=sharing

Please add a screenshot of how it looks like. :)

Why can't I see it when it is launched?

Hmm i think it depends if the window is full screen. I see in the journal when it fails: meta_window_set_stack_position_no_sync assertion 'window- stack_position = 0' failed

Update: so I confirm that when the firefox is taking the full screen launcing the blivet app will fail with the error above. Ths is an unresolved bug https://gitlab.gnome.org/GNOME/mutter/-/issues/930

Interesting, blivet-gui correctly starts in the foreground when Anaconda was launched from the Welcome to Fedora window. If I launch Anaconda from the launcher blivet-gui always starts in the background, even if the Firefox window is not maximized.

Also noteworthy is that some applications start in the foreground and some not (when starting Anaconda from the launcher): blivet-gui and Eye of GNOME start in the background, Nautilus and GNOME Weather start in the foreground. I'll try to look into this some more, maybe there's something I can do on the blivet-gui side to make sure it is always started in the foreground.

Looks good to me.

The issue with blivet-gui starting in the background will be most likely fixed in GNOME or blivet-gui itself so I don't think it should block this PR.

Thank you, then this is fine.
