On the class query page such as this the class sections are listed separated by professors. However, I am unable to tell if a professor's class/GPA is relevant to me (example) because I don't know when he last taught the class without clicking on each one individually. This doesn't sound like a huge ordeal on paper, but I find many classes have listings with professors that have moved departments or left.
Since I like to view class data when choosing my next professor, I would love to have the 'Year' column in the class query page where, next to the professor's name, there is their most recent semester of teaching (that class).
