A very visible method of adjusting the size of the font is needed. If it was there I could not see it. Many people using this site will have diminished vision and need to enlarge the font, it is nearly unusable for me. Thank you.
I can see what you mean about adjusting the font size. Many people with diminished eye sight enlarge the whole screen for better viewing. I believe that there will be many changes for the better as Family Search continues to improve.
Please note that as with most Windows applications
using CTRL PLUS and CTRL MINUS
(using "+" and "-" )
will allow you to set the screen size (including fonts to the size you want)
