Callout textbox in Sentence Diagrams
Add callouts textbox in Sentence Diagrams, since it is not clear where a simple textbox is attached when added to a diagram element. The main purpose of a diagram is to make clear what it try to illustrate, so make it clearer!
Some resources, like The Lexham Syntactic Greek New Testament: Expansions and Annotations, contain all the morphological and syntactic elements to allow an auto generation of line sentence diagrams. What about a tool which parses such resources and automatically build a diagram? Is it too much?
Also, allow synchronization between sentence diagrams and bibles, so that when pointing a word in the diagram, the same word (perhaps with interlinear box open) is highlighted in the current bible.
