In the talents trees it's specified if a talent is:

- Passive/Activated

- Permanent/Not Permanent

But I think it would be useful specifing too (with some symbol):

- Ranked/Not Ranked

I agree with this. Whilst the section on talents does explain whether a talent is ranked or singular, it would be a time-saver (and make sense, given what's already listed in the talent tree sections) if it was included.
