The old "QuickApps CLI" repo will be deprecated in favor of the new "QuickShell" module.
QuickShell is basically the same "QuickApps CLI" but packaged as a module, this allows a much easier instalaltion and configuration. (Simply install and you are ready to go)
Being a module introduces several advantages, for instance, it may include a Web interface (among others things) in the future.
Repo here:
Check the README, it includes information about a FAQ: "How do I use install/use it ?"
Enjoy!
