I just returned & noticed lots of changes, most are explained very well.
I noticed some of my gear has a symbol on it, it looks like a page or something.

What is it & what does it mean?

Another thing I was wondering about is the circle on the gear, some are hollow, others have colors, what does that mean also?

Im not sure if this is new, or I just forgot, but cant find info...

Any help is greatly appreciated. TY in advance.
