The Canvas Gradebook team is kumbayawesome.
Since my institution is just now begging to the conversion process, I've not had much experience with Grades yet. So beyond learning the "new" things, this was great info in general for learning gradebook.
Canvas is open source with how they get info etc .too--all the updated came directly form user feedback. Its not just about how to make canvas better, but to fix overall problems
Five main categories for improvement (my screenshots don't want to embed, so I have attached them)
Crosshairs--will help you see missing work, late, etc.
10 colors to highlight docs
Grade settings coming into the gradebook!
Speedgrader preview--can see and add all the comments on items; in Beta
Post grades lets you automatically mute grades
Can assign a grade until something is submitted and/or auto assign 0s for late work
Students will now just see the things they care about first and same for instructors and observers
Ungraded and uncalculated assignments can be made !
Grades will soon be even better!
