Heart beat for better duration tracking

I have solved for myself using a custom page_duration event with duration property and is a middleware in my react router. It also parametrizes the paths to /page/:id/module/:id. It works but the experience of using event properties for visualization is clumsy I feel. This could be a library feature in react!

Hey! This would be very helpful.

hey this would be very useful for us.

Is there an ETA? Most analytics services have problems with this, which could set OpenPanel apart with this feature. Since OpenPanel is event-based, this could perhaps be solved with the Page Visibility API instead of a heartbeat. If hidden, send the event session_idle_start, and if visible again, send session_idle_stop or something along those lines. The time in between could then be calculated from the duration or used additionally for an idle metric. I have no idea if this is easy to implement, but that's how I imagine it as a non-programmer.
