The ability to fully remove older FDR logs so they are completely removed from the list and don't take up any data (maybe adding a delete button and a confirmation like "Are you sure you want to delete this log")
FDR logs showing how much you earned on that specific job when you click on it and hover over the job (used to be a thing but now it suddenly isnt?)
