20+ years ago, Lindows had a great app store that let you create an “aisle” of your favorite apps so if/when you’d reinstall your OS, instead of searching and installing all your apps one-by-one, you’d just go to your aisle, click “install all” and boom.
Is there anything that exists like that today?
Aren’t most app configurations and settings saved in the user’s .config folder? Again you have to know to look for this, but that should be most of your settings right?
/home/[username]/.config/
