Deckyloader is a plugin hub for all sorts of customization and QoL tweaks. I mainly use it for color customization, artwork changes, ProtonDB icons, and HowLongToBeat stats when I’m deciding on a new game.

I also use it to download custom boot animations and sounds. It’s mostly geek tweaks but gives you a sense of extra power over your device on the game mode side.
