Below are a list of URLs that can be added to the file manager inside of XBMC KODI. The first two are Fusion by TVADDONS (aka XBMC HUB) and Xfinity by XunityTalk and are of course by far the very best.
The rest of the list contain other add-ons you may or may not be aware of but are still very good and worth a look. Some are a copy of the first two and some contain rare and high quality unknown KODI Add-ons most have never seen before.
