ATTENTION: as already written in other threads, all these talks about Python3 compatibility are nonsense because when a plugin is already in the feeds of OBH 5.x it is surely compatible:
if they are in the feeds, they are already compatible, otherwise I wouldn't have told you to download from there!
I myself have it installed and used in both 5.0 and 5.1, although nowadays I don't need it any longer.
So, download it.
And what is said for this plugin is true for all other ones: there is no incompatible plugin in the feed downloadable by green panel. I hope I made myself clear enough.
