To avoid rm mistakes in the future, you could set an alias that always provides the "-i" flag which makes the command prompt you with y/n before the deletion. Another solution is to alias rm for trash-cli commands to move files to the trash like when you delete files in your graphical file manager.
Same. Also because of the Steam Deck now some of my games that previously didn't work at all can run flawlessly in Linux after getting Steam Deck support.
