Thank you so much, comrades! I am feeling pretty comfortable with linux mint, and now would like some suggestions for some absolutely necessary FOSS or free license software for the OS. So far I have the standard, Firefox, ThunderBird, LibreOffice, yada yada. Thank you again to everyone on the linux comm! 
For Flatpak apps, along with Warehouse, Flatseal allows you to view and edit permissions for each app, which is not only useful but sometimes mandatory when an app has misconfigured permissions
Oh yes, Flatseal is also a good tool to have! Thanks for adding that!
