Hello! We have an app for motion animation. We need to understand how long the user is working in one mode or another. We are particularly interested in those functions that are enabled from the start. 
For example, we have an 'autoposing' mode, and it is enabled from the beginning by default. How could we know how long a person is using it before they switch to another mode? 
Another example is the Twin machine function. To use it, a person repeatedly presses the forward and backward arrows on the special tracker. How do we keep track of frequency and time of Twin Machine using?

Now we have invented an event ‘activity mark’. It is sent every 3 minutes if there has been any activity in the program during that time. We are thinking of attaching "twin machine" (if the twin machine arrow has been used at least once in three minutes), "Autoposing" (auto posing was enabled and the controllers moved at least once) to this event property. But this solution doesn’t seem very elegant and easy...
