Different Favicon for each site on Admin bar

The plugin’s main page description implies you put each custom favicon.ico in the theme folder for each site ~ I tried this and it worked! So you have to have a separate theme folder (in my case I have a different custom child theme for each sub-site) and then Multisite Enhancements simply looks in that folder for a favicon.ico. It might work with a .gif also, I didn’t try that.
