Thanks for your post! Browse and keyword search results currently default to "standard" (ascending) date order, but you can specifically instruct ePADD to return results in ascending/descending date order via the advanced search interface, available in all modules. You can also define a date range in advanced search, in combination with other search criteria.
I hope this helps! Please do share any additional feedback as we use it to help prioritize future development.
