I frequently decide to curve a quiz or exam but the curve feature in Canvas doesn't work the way I would expect it to. What I want is an easy way to say "add X points to every student that received a score for this assignment". I can do it with the Fudge points within SpeedGrader but having to manually do it for each student is extremely time-consuming and error prone. Alternatively I could export the gradebook to Excel, modify it there, and then upload it again. However, this is also far more convoluted and time-consuming than it needs to be and again there's an easy opportunity for errors to be introduced.
The fudge point concept already exists, why not make it easy to apply universally to an assignment/quiz/etc.?
