Time Tracking limited to one Task

[mjut]

I am looking into Kanboard for a possible project management app for our team of 10 employees.
What I am finding confusing is the time tracking feature. How can I use this properly? I am running into the issue that when starting the tracking I am forgetting about it. I then browse to a different project and start another time tracker.
How can I avoid this? It shouldn't be possible to track multiple task at simultaneously – additionally, I should actually see the time being tracked on every screen. something like a „status“ in the top-bar of Kanboard?
It would be cool to hear others opinions on this. Or How do you track times accurately?

Thanks!
