Did a lot of work today on creating and testing output for specific lot/title combinations, as cell sequences, and rendering them into TSV. I've also re-worked the lot-based view a little to add precomputed values of all kinds that I need for the spreadsheet, and completed more functions that retrieve properties and titles according to various parameters. It's getting to a point where I can see what now needs to be done for the first target output spreadsheets, and I've sent a couple of questions to JSR regarding precise details of what's required, where the plan was a little vague.
