Steam Big Picture Mode - ever use it?

I use it mostly with my Steam Links

Only ever when I need to do something (set up/troubleshoot) with my controller.

I think I've hit that button by accident a couple of times.

Yes, on the Steam Deck.

Steam always runs in the background, so the BPM wouldn't be very helpful if it would run the whole time.

I used it a lot before they updated it to look and function like the Stream Deck.
Some of the features either got trashed or aren't accessible anymore.
Like knowing the battery life of you controller is gone.
Some of the custom controller features are gone.
You use to be able to get very very old games that didn't want to go full screen to do so or fix resolution issues.
A lot of people either hated it, didn't know it existed, or like me relied on it a lot when using a TV/controller.

It's a good idea on paper, and probably a very good idea if you're trying to emulate the feeling of a console. But for people like me that like to multi-task and surf the web it just kind of gets in the way.

I enjoyed it when connecting to a TV but otherwise eh

Only when using a controller, or when connecting my pc to a big screen.
I believe there is no other reason to use it, but it is a good feature.

I honestly cannot even figure out what this ugly interface is meant for. Besides bugging me when I hit the wrong button.
