Import in SelfControl #908
Description
Is your feature request related to a problem? Please describe.
I'm always frustrated when I have to manually import every domain.
Describe the solution you'd like
I want the app to have an import button when clicked lets you select a *.txt file and then automatically upload all the domains in that.
Also to automatically check for updates and notify me when there are updates.
Describe alternatives you've considered
I currently have to copy and past the whole thing, the domains I wanted to block.
