There are a ton of plugins others have built that we take advantage of and will continue to do so until I feel comfortable building my own. Here is a list of several that I frequently, how I use them and where you can find them.
There is a wide range of reports, plugins and customizations available. There are a large number of free options available and some other more elaborate options in their paid section. The cost of the paid options depends on the number of students you serve, but was very reasonable considering the amount of time it takes to develop and maintain them. Rather than list all of them here, or even try to pick my favorites, it would be best for you just to check them out for yourself.
