Manual flight logging, which will answer this request, is in version 2.4.2 which should be out this week.

My club, and the group I'm in also log brakes off to brakes on, but we do this by adding 5 minutes to the take off and landing times, this seems to even things out. If I forget to log the takeoff times etc, which I often do, I use the times from SD

Within our club, we log brakes off to brakes on times. Other clubs log engine start to engine stop and Hobbs readings.

Adding simple menus to record this data would be of assistance in such instances. We have no interest in noting airborne time - the fuel starts burning once the engine is running.
