Document based vs One Main Window

After looking at NEAT Receipts yesterday and a few other programs, I’m beginning to think that my decision to make ReceiptWallet a one main window application may not have been the best one. A huge advantage to multiple windows is that people can have data files for each year or one for work and one for home. Unfortunately, changing from the main window to a document based model is not easy. Unfortunately NSPersistentDocument doesn’t support packages, but a few developers have figured out how to get around this. What does this mean? This would mean that all the data is stored in one package and it would appear as one file, but would actually be separated inside. This is exactly what I’d want with the database file separate from the actual PDFs.

Hmmmm…
