I think I read nearly all KB articles so I can say everyone who uses maps wants a feature to easily rescale the font-size of for examples map tables. The only way to do this is via the custom.css sheed. But this way isn't supported by Paessler (I fully understand why!) and the customization could be overwritten by any upcoming update.
In my opinion it would be really great if we get an option or at least a supported well documented and explained way how to rescale the font-size within maps. Sure, the custom.css sheed could be an option, but therefore you need as a customer and even as a partner a good knowledge in CSS. This shouldn't be a requirement by such a good an user friendly product like PRTG.
