When I select an exercise on a track with a learning track, if I am not yet able to do the exercise, exercism will list the exercises I need to do to unlock it. This is great. It also shows a little padlock on the exercises I haven’t yet unlocked. Also great. But neither of these is actually the information I want. I want to know which exercises I need to do that I haven’t already completed. This information is not obvious on the exercise page. The only way I know to figure it out is to open all the listed exercises and see which I haven’t completed yet. Not great.
So I guess this is a feature request? On the page for an exercise, on the left where it tells you how to unlock a locked exercise, I want some hint as to which of the listed exercises I’ve already completed. Maybe they have a green background or something?
