Feature description

the current pencil size control is a slider bar that don't have a precise control of the size, so if you draw something at a x size and then change it to a y size and then you want to go back to the last x size, it is hard and you will pick a size that is at least similar to that x but it's not its exact size.

by creating a limited row of sizes like this in the drawing below, you can have a more precise control of the pencil's size:

Why do you want this feature?

like the reasons i mentioned before, a lot of times i'm drawing something and then i need to change the pencil size and when i want to comeback it is hard to set the exact last size.

Maybe as an setting? Having the choice sounds like a nice idea.

I am also annoyed by this. I suggest adding a numerical field on left side of save button which tells current brush size with numerical value. When you tap this number keyboard is opened where you can fill a new value. Also the numerical field would be updated when you move brush size slider.
