Hey MariBeth - thank you so much for your question!
This is something our team is looking into working on. We're looking at adding a date-sort feature into the "My Contributions" area at https://crowd.loc.gov/account/profile/. This way, you can get a quick sense of what you worked on and when, and what the current "Status" is of each of your contributions.
I'm going to share your note with our development team so they know there is still interest in this! Please let me know if you have any further ideas!
