I’ve implemented more example badges. They are available in the latest version (v0.1.46).
The filter result badge will be the most interesting for most users. You can use the Filter Gramplet in the sidebar and the matching results in the tree will be highlighted with a badge.
Below you can see an example where the filter searches for all people with “Garner” in their name and the matching people in the tree have a blue bullseye badge.
Hope this is useful for some of you!
