Discussing with my team-mates this morning but we're not sure which one is the best way.
Scenario: When users select a single document to process, they will see a progress bar and text displaying its progress (ex: page 35 of 40).
When users select multiple documents, the current implementation is that they see two progress bars. The first one indicating number of document that is being processed (ex. 13 of 30 documents) and the second one indicating the pages that are being processed for a specific document (ex. page 20 of 1000).
It would be ideal if the system knew the total number of pages in all documents so the progress bar could reflect this in real time. However, it's not going to work that way. We only know the current document's total pages.
I want to get rid of one of the progress bars, but at the same time matching the dialog when you only have one document (showing the number of pages that are being processed). But also I feel that total is more important than one document. Maybe keeping two progress bars isn't that bad of idea?
