High contrast mode
It would be nice if high contrast mode also made all or most fonts darker (or perhaps this might be a separate preference setting - font darkness).
Decades ago text was almost always presented as black on white with generously spaced easy-to-read fonts. Now text is often presented with low contrast between the font and background color, and with tightly spaced fonts. Form too often superses function ... which is unfortunate for those with poor eyesight ... which is nearly everyone as they age. I suspect the aged are a significant percentage of those interested in genealogy.
I love your site, and the good works you are doing.
