Do you need to easily view and edit your user properties?
Do you want to collect/search/filter based on your user properties?
Do you collect and display key figures & graph about valuable actions performed by users in your product over time?
Integrate subscription info like upgrades/downgrades actions?
Do you have this info always at hand - mobile and desktop?
These are things I'm struggling with since it seems not directly adding customer value if you're building these things, but somehow the value is in getting to know your customer better...
