Text size for Ruler and Nameplates?

Is there any way to scale the text in Roll20? Specifically, we play a lot of "large" maps (150+ x 150+) and as GM I find myself zoomed out quite a bit to make sure I can keep track of everything. The problem is, when I do that the text size for nameplates and the ruler gets so small I'm constantly zooming in and out during the game. It's playable, but obnoxious. Am I missing a setting or am I stuck with this?

The zoom feature is not selective of what it zooms. It's all or none, just as if you were zooming with your browser or accessibility tools. It's an admitedly odd suggestion but might actually fit your need. Turn on Windows Magnifier. It sections off a portion of your screen to show you a zoomed in version of where your mouse is. You can resize the zoomed-in window and drop it in a corner of your screen, allowing you to have Roll20 zoomed out but still show you more detail wherever your mouse is.

Is that something that could be changed in the code?

Possibly with some unsupported manual .css replacement but that's really not my forte.
