Great app - very simple, very straight forward, does exactly what it says on the tin. It would be amazing if this app would be further developed in the future, keeping it's very simple and focussed interface but offering additional options to people who would like to have them (such as split times, gap to leader/opponent in front, number of pitstops, flag shown at position of racer, time left in session, time passed in session / laps passed, laps left, ...) Those are just a few features I would love to be able to optionally have. One feature that is sorely, sorely missing in any case is a button straight on the app interface to "keep app window on top" and perhaps an alternative app window skin that is more transparent and "floaty" so the app is easy and pleasantly to use OVER a fullscreen running Assetto Corsa session.
All in all I gave this app as it is already 5 stars as it works flawlessly as advertized. It would be great if the app stays with us as some of the other "cannot live without it apps" we have already and gets further developed.
