I was looking at the Courses Tool and noticed a few things, not all of which are potential bugs. :)
First, I found it a little odd that there is not a filter for license type. It's lovely that we can filter our library that way, but since temporary courses are touted as a subscription feature, it seems natural that a user might want to see what courses may go away soon.
Second, it does not seem that all courses I've started are listed under the "Started" group. I began one of the courses (NT202; it has a temp license for me) and I've gotten through four or five segments, but it is not listed under the "Started" bunch. Both the desktop app (Window) and the mobile app recognize the progress.
Third, the tool initially showed 7 courses as "Started", but I noticed that some of them I had not touched in a long time, and I saw that several had been temporarily licensed. So I deleted the plans of the temporarily licensed courses. After I deleted several (maybe 6-8 of them) of those plans from the tool, I noticed that there were still 6 left. It would seem odd if only seven were ever listed, and I didn't really pay attention if each time I deleted one, another course I had started popped up to replace it. Incidentally, NT202 still does not show up under the "Started" group.
It seems that these last two things are bugs.
