The inbox needs to be revamped. It is so hard when we are processing hundreds of invoices a day and there are items for review, distribution, final integration errors, etc. all under the same inbox.

I think you should be able to have different headings and those invoices then fall under those headings. This would help make things more clear.

I also think if you're an approver and supervisor - you should be able to see what was escalated to you vs what you need to approve vs what you need to review.

Also, if you're mentioned in a comment - there should be a section for that as well. That way you can easily respond back and forth as necessary. Right now you can only find the invoice you've been mentioned in a comment via email. Some of our users have Internet Explorer as their browser due to another system they use (their main job needs to use IE) so if that is set to default, it's impossible to be able to find that comment.
