Themes/font sizes

Is there a combination of settings that will make SAGE 100c readable in all windows? I can enlarge the font in the launcher, but the field labels font in the module windows is so small and hard to read. If I change to the Classic theme, the fonts are larger, but the tab color is dark grey with black type, so one unreadability issue is exchanged for another. I've seen reference to the ability to change font size in 100c, but I can't find anywhere to change the font size displayed on module windows. We have two separate companies that we enter information into, and we have company themes set up with different colored frames to ensure we are in the correct company. In my user maintenance settings, I have the theme code blank, because I believe if I don't, then the company themes are superceded by my personal theme. Can anyone offer advice, or is this still something that has gone unaddressed by Sage? When I open a window in Customizer, the fonts are nice and big, but revert back to the minuscule font afterward.
