I know you can sort the hits based on when they were posted (newest first, etc.) but it seems it might be helpful to know when they were first put up ... sort of a time stamp. The hits in the middle seem to get lost in the crowd.
Yes, that would definitely help, especially when you have not been to mturk for a few days and wish to check all the hits posted during those days. Let's hope Amazon brings some positive changes which are beneficial to all - requester and workers both.
