This Annotation Pane (Annotation with Links, Notes, Tags v3)
and perhaps this Updated Stack script V1.0: Create stack of multiple cards/snippets for each document with backlink and Wiki-group link, cited text or blank note, comment, tagging by ordinary tag and group tag
And maybe this for consolidation of bits pTags V1.2 (Updated Version) , the pivot table of tags with refresh function
Not trying to say that these scripts as exactly what u are referring, but to show you that DT3 can do many things, but specific development for specific purpose is a function of user’s effort.
