The Crocodoc tool needs serious improvement or replacement. I last used Canvas four years ago, and Crocodoc was broken then; I have now returned to Canvas, and Crocodoc is just as broken. The problem is the text comment and highlight tools, which do not work at all on Chrome, and which work poorly on MS browsers. If a tool doesn't work on the most widely used Windows browsers on the planet, it is by definition broken. We don't need a workaround; we need a new tool. Moreover, it would be great to have an application that has the grading tools that I used with TurnItIn: the ability to mark issues with grammar, punctuation, and composition. Crocodoc feels like a relic from 1998, and it is very frustrating.
