I suppose I should first start by saying Thank you to to the ZorinOS team. You are creating without a doubt, one of THE BEST Linux distro’s available to date.
I am a long time Windows user as well as a long time Linux dabbler. My "Go TO" distro was/is Fedora Core, SUSE and Mint. I have tried MANY distro’s in the past. Always with the goal to dump windows. Dare I say you are the FIRST distro where I have formatted my Del Insperon 7773 17" laptop and installed ZornOS.
I am a legally blind individual. Your font control while nice, does not quite do the job.
It would be nice if one could adjust system wide fonts as well as scroll bars.
