Aside to Kirk: Thinking of the potential to represent morphemes, morphological annotations, syntactic analysis, with variants in a first person shooter, sorry, point and click interface. First step display, then authoring.
Hmmm, some relationships could be auto-generated, such an an emendation need only be entered with its relationship to a morpheme and its relationships to the word, verse, syntactic divisions, etc. could be automatically added. Could have “display changes” to facilitate review.
