Changing footnote display font?

I’d like to find a way to change the display font for footnotes (and annotations for that matter) so that it shows as a smaller font and perhaps a different color. Can this be done? I know about ghost notes mode, which is pretty good, but I’d like “more,”

Thanks in advance

You can only change the font in the same way as you change the font of any other text, via the fonts panel; there is no way to have annotations and footnotes automatically use a different font.
All the best,
