To avoid collections, this is what I would do:
- Type a * into the Search field (which will present everything in the Binder as a flat file structure)
- Switch to Outline view, make sure Modified Date is one of columns (Ctrl-click the column header to add if it isn’t), then click that to sort by it.
Then you will see your project sorted by Mod Date and you can click on any document to see the whole thing, and use the < Back key in Outline to get back to your sorted list.
