The enter to start and s to skip is very poorly thought out. I find myself forgetting enter literally every time and I've been though 20 or so lessons, and when the lesson starts with s, I press it (forgetting the enter) and skip the lesson. I don't know how to go back to the last example (undo the skip), and now I have to fucking pick a different lesson in the drop down, then reselect the one I was doing, then skip over every example I did, then fucking press S again because I forgot enter, and have to do that shit again. If you're going to design something, free or not, do it fucking right. Your product made me mad enough to actually post this.
