Sorry I do not know what it is called, but would it be possible to not have it prefilled:
I would like to start typing math notation without having to delete this equation every time. I know it is there to show what the function is capable of, but after the hundredth or so time it becomes a little cumbersome to delete before I can enter the formula I want to enter. If you are trying to emphasize what it is capable of, can you just have the drop-down math keyboard appear when you click the plus? I would like to start typing after I click the plus without deleting the default equation every time. Thank you.
