I was curious about possibilities for tagging text in such a way that tags overlaps. For example, I'm tagging titles of poems, but some of these also include names of individuals or places that I also want to tag. This works in some cases but not others. (i.e. after tagging a string of text and highlighting a string within that tag, the option to add another tag is not available.) I'm not sure if this is a case of a bug, limited functionality, or me trying to do something that isn't really sensible in the first place.
