> documentAndPdfSavedOnDiskJsonStates

1. Why is it the document and the PDF? Are they the same thing? if so, pick one term and use it consistently.

> SavedOnDisk

2. Disk is the default place to save things.

> Json

3. JSON isn't an interesting label, as it gives you no ides of the data structure. If this is a hashmap with a bunch of document titles and booleans with their save status, then that should be obvious.

This thing seems to be save state for multiple documents, right?

So I'd replace:

> documentAndPdfSavedOnDiskJsonStates

with

    documentSaveStates

or

    pdfSaveStates
