Be able to see what items are available for clan mates based on TH level
I often get asked by a lower level clan mate what they should upgrade next. As a TH9 I really do not remember what level a Wizard tower can get to for a TH6 or how many of a certain thing they can have.
It would help if I went to their base, clicked on their TH and could see all the items they could have, what quantities, and what levels. For example, they can have 3 Wizard Towers at a max level of 4 for their TH level. Then I could make more informed suggestions to my clan mates.
