Hi there, I was just about to watch my 3D structure video, but the video for gesture came up instead. I've inserted a screenshot for your reference. Two suggestions: - The ability to unmark a lesson as complete would be nice (I can see myself going through the course once and marking lessons as complete, then wanting to unmark them all and tick them off again as I revised them for a second time. Idk, I like lists, so having that flexibility would be nice. It would also suck if you marked one complete by mistake. Ticking something off when you've finished is so satisfying...) - That 'remove course' button looks ominous and scary lol, and it frightens me with how close it is to everything else. Could just see myself clicking it rather than the expand window. I daren't try it to see if you do get an 'are you sure' prompt – but if this is where that button must live, an extra window will help prevent misclicks.
