One of the most useful features in my TMG program is “flags.” It allows me to highlight characteristics of individuals and then display icons for them. For example, I flag the immigrants in my tree, then display a tiny globe on their personal page; I flag DNA matches and their paths to the MRCA (if known); I flag direct ancestors, etc. I can then print a variety of reports or just group the people in my tree. The flags are applied in my genealogy program, TMG, and the icons in my website program, Second Site. To see how I use them, please click https://doriswheeler.org/, scroll down the home page to see the icons defined, then view them in the Surnames Index and on individual person pages. Here are examples: http://doriswheeler.org/i28.htm#s2197 (scroll down to see icons), https://doriswheeler.org/g0/p56.htm#i1654. Icons are associated with the names of people.
I’d love to see this feature added to RootsFinder.
