     * USE THIS SECTION TO TELL US IF THE SERVICE COULD ALSO COVER OTHER USE CASES AS WELL. AS AN EXAMPLE PLEX IS PRIMARILY KNOWN FOR MANAGING MOVIES, MUSIC, AND TV SHOWS SO IT REALLY BELONGS IN THAT CATEGORY. HOWEVER PLEX ALSO NOW HAS PERSONAL PHOTO MANAGEMENT WITH AUTOMATIC MOBILE UPLOADS THROUGH ITS APP, THAT NEW FEATURE CAN BE LISTED HERE, INSTEAD OF ADDING PLEX TO MULTIPLE CATEGORIES. IF THERE IS NOTHING TO PUT HERE, THEN PLEASE DO NOT ADD THIS "ADDITIONAL CATEGORIES" SECTION.
 
+    * IF THE SERVICE HAS A SEPERATE APP FOR THE ADDITIONAL FUNCTION THEN YOU CAN ADD IT TO A SECOND CATEGORY INSTEAD OF LISTING IT UNDER HERE. AN EXAMPLE OF THIS WOULD BE NEXCLOUD TALK. NEXTCLOUD TALK HAS ITS OWN SEPERATE APP JUST FOR THE COMMUNICATION ASPECT OF NEXTCLOUD. SO NEXTCLOUD IS LISTED UNDER "FILES/GENERAL" AND "CHAT/COMMUNICATION"
