Make "track daily fitness" or something to that affect on the top menu and allow it to either run co currently with the fitness actions (gps running, tracking, cycling' etc).
The fenix and tactix acts just like the vivofit, but I have to pause it if I want to start a new work out, orienteer, etc....
Allow the DFM (daily fitness monitor to run in background without affecting other activities).
may drain battery a little faster but charge mine daily anywayq.
