The plugin on his own is quite good but talking to the author for support is a terrible experience.
My concern was a synchronization issue with MPDB. Basically when you use MPDB, MPDB synchronizes the gadgets items but they are not functional, even though it is coupled with the restore-cosmetics function of its plugin. Whether or not it's his plugin that restores the gadget item I don't see what should stop the gadget from working as long as an item corresponds to a gadget and his plugin has restored the fact that the player should have the gadget enabled? When there is a compatibility issue between two plugins, one of the two plugins must take care of it.
Maybe there is a deeper reason that I don't take into account but it doesn't change the root problem: The author will answer to your questions with very short answer, and will eventually ignore you as if you are annoying him.
