This update features the ability to add track split locations ingame. It will not auto-refresh to show them right away.
To make track splits, after opening up the app, click the cog icon. There you'll see a few buttons.
The first two will toggle driver names and split locations visibility. These values are not stored but can be manually set through CM or settings.ini.
The other ones can be used to set split locations. Simply drive the track and whenever there's a new "Split time", click the appropriate button. The split time changes again when driving over the next split, so click the next split button, etc. The order of which you click them doesn't matter, so if you think you've got correct split 1 and split 2 numbers, you can drive over to your split 3 and click 'Set split 3' to redo it. I tried automating it but failed, so this'll have to do
The finish line is set automatically at position 0 and doesn't require any manual input.
The numbers are stored inside the tracksplits.ini. It now also contains split locations for all Kunos tracks.
