screen ruler too small

P21 has enough visual GUI control so menus, panels, tools, etc. are nicely sized for legibility and use on my dual 27" 4K monitors. PC win10

But, the rulers are tiny (see jpg attached) and I have not found any way to enlarge to make them readable and consistent with the rest of the GUI.

So suggest this is a small but easily fixed bug for 2021.1

Thanks
