This actually happened a few days ago but nobody's mentioned it.
Buy the key (or update if you sideload from your phone) open it and select the option to hide the app icon.
Done.
Does this app allow you to set file and folder permissions within the system folder?
Right after I messaged them about the pro key they added it to the app store, also i had to sideload the chrome browser to add Google drive access for cloud storage.
Did that yesterday and it worked great.
Damn this beats every other file explorer on Android TV, it's fast and beautiful, navigation is logical, it has network browsing, etc
