I ***finally*** got things set, with much difficulty, to colors and fonts and sizes that I mostly can see (slight to moderate visual impairment...I can "see" pretty well if things are not tiny and are contrasty).

I even finally got a theme working with black font on a light background in the taskbar labels (hooray)...but it isn't big enough.
My question is...is there any way to modify the theme I am currently using to do just one thing: make the taskbar font a few points larger?

I saw theme editing over in 7 forums
Edit .theme files Solved - Windows 7 Help Forums

but since 8 is so different from 7, thought I should ask here.
