On logging in today, I noticed that the PDFs listed under 'My Downloads' are now organized by type, and that each type category can be expanded or minimized individually.
If this is a new feature: Great! The improvement to readability is much appreciated.
If this is an existing feature I just turned on somehow: What took me so long?
Mine allow to sort by name or group by company. The groups can be minimized. This has been around for probably a year or so. Is that what you're seeing?
