The few apps with working delta timing for linear tracks (Sidekick, Multilaps) sometimes don't work - here's a new solution, again with big help from Schlaubi77.
The delta timing comes in a separate app window, a third app window allows reference time selection.
You can choose reference files from the same car, other cars, or other players (files have to be exchanged manually)
Thanks to help from Schlaubi77, settings can now be configured in Content Manager GUI
