Member focused analytics is strongly needed and a big miss in the current platform! Currently, the only way I've been able to track membership flow (New members and cancellations) are via the automated emails. I have auto folders set up in my gmail to consolidate the cancellations each month. I then manually confirm this and track in a Google Sheet. It's archaic!
Would also love to see basic data such as last login, number of logins, content viewed, etc. The ability to monitor this and then automatically email non-engaged members is essential!
