I will say that since using the hot keys this is no longer a bit deal for me at all
it could be a first impression improvement though minor.
I would like to click by increments and see a current value shown. so 6 buttons instead of a slider.
-35ts -10pts -1pt [VALUE] +1pt +10pt +35pts
or maybe 1pt 12 pts and S for show slider (once slider is shown you only can click once to select then it will return to the buttons) if you didn’t land where you wanted just press s again.
I find slider is great for large size differences not small.
I would also make everything to intergers fractions could always be inserted by way of typing.
would be nice. as an option of course.
