One of multiple areas the Steam Deck has the edge over its Windows alternatives such as the ROG Ally is the more open nature of SteamOS. It's not as wide open as most Linux distros, but there is certainly more license to tinker and customize than you're allowed to do with Windows 11.
Since finally getting acquainted with Decky Loader on the Steam Deck I've been playing around with all sorts of customizations. The latest is pretty simple, but I'll be damned if it doesn't make me smile.
