ProtonPlus is a useful tool for managing compatibility layers like Valve's Proton, GE-Proton and more on Linux, SteamOS and Steam Deck.
While many will likely know of the popular ProtonUp-Qt app that I've covered here a lot on GamingOnLinux, ProtonPlus has been steadily building up a real nice list of features and it might even be time to switch over. In fact, I actually vastly prefer the UI design in ProtonPlus - it's a lot cleaner and super simple to use it. Not that ProtonUp-Qt was hard, but options are great.
The app supports managing Proton for Steam, Lutris, Heroic Games Launcher and Bottles. With support for various different community versions of Proton along with other tools like Luxtorpeda, Boxtron and Steam Tinker Launch.
With a recent update to the app in June, it now has a page where you can view all your Steam games and individually change the Proton version used for them.
On this page there's various sorting options, you can also adjust launch options, and there's a button to go right to ProtonDB too.
Check it out on the GitHub page.
Confused on all the different versions of Proton? We have a guide here on GamingOnLinux to help clear that up.

Looks great but as KDE user, gnome adwaita UI just mismatches so much and doesn't layout in ways that make sense to me. I don't expect the devs to drop everything and add KDE/Qt into the app as that's completely unreasonable. For now, I'll continue using protonup on my deck and desktop until something like protonplus comes around that fits my desktop environment.

I don't remember hearing about this one before. Always just used ProtonUp-Qt like most, and it does work perfectly fine, but this looks a little better when using Gnome (you know, for the 20 seconds a month it gets used). Glad there's options out there.

ProtonUp-Qt also has this feature.

ProtonUp-Qt has this feature also.
Sure, options are great, but I'll stick with ProtonUp-Qt as an avid Qt fan and who has contributed a couple features to ProtonUp-Qt in the past.

Does KDE not offer a way to make GTK applications look uniform with the rest of the desktop? On GTK-centric environments, there are several options for Qt applications. For example, I use Kvantum, and all of my Qt applications look exactly like my GTK applications. There's also Qtct, but it can only be used for Qt5 or 6, not both simultaneously.

Before adwaita, yes things were better. But no design language and how adwaita works just does not port to qt and no real efforts to make stuff cross DE for adwaita apps have been very successful (that I'm aware of).

@TrainDoc Ah, that's a shame, but also quite surprising. Qt is used quite a lot, especially since it has multiplatform support (so does GTK, but it has to be implemented in a weird way on anything other than Linux and BSD, so it doesn't really exist outside of those in the same capacity). One would think a translator existed by now, but maybe we'll get one soon.

@joom it did until GNOME broke sh*t.. still works fine with pre adwaita and adwaita apps you can force it to use breeze with an environment variable but because GNOME thinks its the ONLY DE out there don't always work well

To add to that ^, GNOME devs HATE themeing, and actively go out of their way to discourage people from it. In fact, they even went to the extent of making an entire website for it: https://stopthemingmy.app/
This extreme user hostility is why I boycott the GNOME ecosystem.

@d3xt3r yeah I get it. This is why I switched to KDE. I like GTK/Adwaita, but the devs are such a pain. At first I was a big fan of them, but the more I got to know the DE the more I understood that they just live in their own bubble. At this point it would be too much for me to rewrite my application in C++ and Qt. If only they listened to the community they could be so much more, but it is what it is.

this looks awesome! Next time I need to tinker with my proton versions I will give this a try instead of up-qt.

hi
I think I am going to stick with ProtonUp-Qt. I tried the Flatpak version, but there was no option to switch the theme to the dark theme. I am running Linux Mint Cinnamon with a dark theme. If or when I get the time, I am going to look into building from source
IMHO, if I were going to develop an application for Linux, I would never touch libadwaita or any new ui libraries from GNOME

@MadWolf I thought the day/night theme adapted across all DE, but I guess not. I'll add an option for that.
