I agree. I have to be careful about creating too many standalone add-ons though as users are installing them all which slows down the “Plugins” page with calls to check for updates. GP Premium is definitely the way users should go if they’re going to be using all of the add-ons.
Something like this is definitely necessary though – people love the floating bar.
As for the back to top, there’s a few plugins out there currently you can Google and install which add this for you.
Thanks for your input guys!
