What do you dislike?
This library is my favorite on the list. So far so good, it integrates with pretty much every front and back end frameworks out there which to me is a MAJOR plus point for framework developers who don't want to build their own libraries from scratch and are not restricted in any way by design choices of this library. It's well implemented also, no random errors all the time that take hours to figure out. The UX is nice if you're into nostalgia and I think we (the team) could go as far as call this one an old-fashioned charm that will never get outdated, sleek and sharp.
