g(Math) for Sheets extra features.
g(Math) for Sheets has the same interface as g(Math) for Docs, with the slight changes for inserting into the current cell instead of where your cursor is in the Doc. It will also increase the size the cell you insert into to make it easier to see the full graph.
The feature that I am most excited about is the QuizNinja and Quick Quiz Creator to create a Google Form that contain math items!!
