I'm hearing reports from my faculty that the tooltips are really hampering their ability to quickly move around in the grade book (see image below). Basically, the issue is that when a tooltip (the helpful message that pops up when you hover over a cell) pops up, it covers up another cell in the grade book and makes it difficult to get into that cell. If this is affecting others I can write up a Canvas Feature Ideas to create a toggle setting in the grade book but I wanted to see if others were having this same issue and if there was anything they had figured out to mitigate the problem.
Adam yes they are a pain. I have not liked them from my first time trying to enter in grades. I am new to Canvas, so I will let you write up the feature idea.
I had the same experience as Ron. The tooltips have been improved since I started using Canvas, but they can still get in the way.
