I have AR151 but cannot use it the course tool since it is 'unavailable'.
The courses tool is showing locked, the library is showing 'permanent'.
May I also add my voice to the requests that the courses tool be completed.
It seems like many fundamental tools are created and released as version 1.0 ... with bugs and UI flaws, but rarely do any see 2.0 or 3.0 status ... new tools or platforms are being sought before the base platform is developed. (Thinking citation tool, power lookup, guides, tag management, labels, searching, context menus (more like context 'marathons' ... too many options ... too slow), library (!) etc.) How many of these basic tools are fundamentally the same as when first released? </rant>
