When someone enrolls in a track, there could be a clear "Start Track" button before the first action, rather than users having to figure out which action to click on first. After completing each action, users could receive a "Go To Next Action" popup that guides them forward, instead of requiring manual navigation to select the next step. These improvements would create a more intuitive and guided experience throughout the track journey.

I'm also aware of our previous decision regarding non-linear learning and that requiring actions to be completed in linear sequence is planned as a future feature.
