How to install 'Cycle Cameras' addon for 2.8x? I'm using a great addon called "Cycle Cameras" made by @CoDEmanX for Blender 2.79b which I'd like to use in Blender 2.8x as well.

Fortunately there already is an updated version by @Matthias &amp; @batFINGER. However, I can't get it to work properly. Everytime I try to install it via User Preferences > Install from File the addon doesn't show up in the list. I tried to install it in Blender v2.80 and v2.81 without any success.



What am I doing wrong? How to install the updated version properly?
If the name of the directory of the addon contains "."s and "-"s remove them. Rename the directories name in a way, that it only contains characters a-z and A-Z. Close Blender, reopen blender and check for the addon.
