Add an option or feature to automatically highlight an entire subsection of the active curriculum displayed on screen. Example: While in a chapter of curriculum, say 5.2.3 I often close all the open or unused subsections like 5.2.2 and 5.2.1 or anything above them to keep from having all that mess on the screen. My thought is I have already taught the previous sections and don't need them open and even though I may refer back to a previous one later it would be nice to have the current subsection highlighted for an easy "return" reference.
