Have created Proton Drive Utility Based rather using terminal. its a Linux App Utility "more a utility then the traditional proton drive app" try and give feed back to the email listed on the GitHub page.

in beta and development but still usable and see what you guys think!?!

also giving more ideas to developers that can do the same or better

with this you don't need to use the terminal you just need to use proton-drive client to login and then use the Graphical User Interface built with ease. still in development. but usable try and see if you like the Linux App
