ProtonUp-Qt gives you an incredibly easy way to install compatibility layers on Linux like GE-Proton (formerly Proton GE), Lutris-Wine, Luxtorpeda and more.
The developer just recently put up version 2.6.1, which as a bit of a highlight should now work nicely with the Flatpak version of the Heroic Games Launcher (for the Epic Games Store). This is especially good for the Steam Deck, where I imagine most people will be using the Flatpak, since it's easy to install and update via the Discover software centre.

Apart from that it also adds a "tool description to install dialog" just to give a bit more info on what you're doing.
See more on the website and GitHub. If you need help, we have a whole guide on it.

and ... tried within the next minutes and ... it's clearly super handy 
Beside it allows to install/remove GE releases, it also shows what game is using what GE release and even allow to switch between installed versions directly within ProtonUp-Qt. When you have a huge colleciton of games, it's clearly more than handy
