The “free” version of your plugin is extremely limited with almost ALL its functions grayed-out and NOT working! Almost whatever function is tried the user is urged to get the paid version! …
However, the reason that eventually made me uninstall it was that, though it recognized folders from a similar plugin I had previously installed, in order to activate them I was urged (again!) to get the paid version! … And that was it! … If this “free” version doesn’t do even that, then of course the question is, what on earth does this “free” plugin do?! … for free?! …
So, sorry then, but I have already uninstalled the “free” version of your plugin, and activated back my previous similar plugin …
