I know gesture function for undo has already been introduced.

But,
I am grabbing pencil in right hand and ipad in left hand, I usually grab ipad for not to be shaken when I am writing, so I have no additional hand to do gesture!! Even need two finger double tap.

Rather press undo button is fast and convinient. Eraser button is very useless for me that I have to press pen button again.

So to press undo button accurately is very important for me to use GoodNotes. But button is very small, even the slightest mislocation woudn’t work. To press again is simply annoying.

Let Button size itself be as it is. Only rectangular shape area around undo button is sufficient.

please consider seriously.
Thank you!!
