As with previous version updates, I don't care what you do with new features and options, but don't REMOVE anything without disclosing what you've discontinued. View the attached screenshot of a "Site Response Time" resource. v8 is on the left. v9 on the right.
I'm pleased you fixed the bug so the SUBTITLE is actually displayed. However, what happened to my Radial gauge? It's been replaced by something called Radial...but that's not Radial. That must be "Radial v2". The original Radial is gone. Another example, in another one of my resources, is Modern Blue. You at least kept this gauge, but you still edited it. I've no problem with you defining a "Modern Blue v2", but I utterly dispise when you edit pre-existing items from a graphical standpoint. Whether the changes are considered better or worse, depending on who you ask, is irrelevant. If you create a NEW "Modern Blue" gauge, you should call it something else.
