well yeah thats how gnome shell will enhance their background apps section in the corner menu. Currently all you can do is summon the application from the background into focus. This implementation will hopefully replace the need for https://extensions.gnome.org/extension/615/appindicator-support/
This is the most annoying thing imo. I like the new proposal… but I want to know all my apps that are in the background. I won’t without other extensions still. I just want things to just work lol.
What's the benefit in replacing one extension with another in order to achieve the same thing? Real progress would be an option in the default Gnome shell to show the background apps directly in the top bar without any additional clicks.
I don't think so. The extension adds support for systrays in an unsafe manner, and after years of that not existing in GNOME (unsafety being a reason), why should it change after some design mockups?
What I could see happening is that now some devs start discussing a new systray API and in the end that would be implemented natively. Hopefully not hidden behind 3 clicks tho lol
Basically, the current implementation is old and insecure in many ways. Gnome isn't completely against the idea (they even have mockups for how it would look like) and there are discussions about creating a better framework for it, but progress is slow.
PS: For exiting apps like Steam, if you're using them as Flatpaks, you can set them to not be able to run in the background to begin with and to exit when you close the window. That can be done either with the command line or with the Flatseal, a usefull app to manage Flatpak "permission".
