I have shared widget libraries with 100+ widgets. It would be great if I could tag them so when some else searches for a widget they can find specific widgets easier with nomenclature they use. For example with a '+' icon I would like to tag it... plus, add, expand, more.
Also, while you're at it if I'm searching for widget and I change libraries please clear the search term. I can't tell you how many times I switch libraries and wonder why nothing is loading and then I realize my previous widget search is still cached.
