Since I'm one of the dinosaurs (over 65) who refuses to use a fancy phone, I prefer Follow/Unfollow spelled out (I read words better than little pictures). That being said, since my time on Earth is limited and the future belongs to the semi-literate young 'uns for whom spelling & grammar don't count, do what the future demands. I'll adjust.
BTW... Thanks for the heads up on what a blank star/colored (am I allowed to use that word?) star mean. I would have had no idea.
Good luck, Dave. Changing to accommodate the future is a difficult task.
