TreeSheets Diagram: Tablature for Seagull Merlin/M4

Just another little creation as I continue exploring TreeSheets for tree diagramming (well, in this case, like the last one, tables that have a "barely-there" tree-like structure).

Click here to view the full-sized diagram.

Although this kind of thing could be done just as well (maybe better?) with dedicated tablature software or with spreadsheet software, I wonder if TreeSheets might be well-suited for storing and organizing a collection of song tablatures and adorning those tablatures with meta-data.

Yet another something for me to chew on.
