Relatively minor, but for GPT-4 users, I think there should be a counter showing the remaining requests that the user can make for the current 3-hour period. I have only recently started using GPT-4, and I currently find it more accurate, or at least more thorough, than GPT-3.5, but I think it’s annoying trying to remember how many requests you’ve already made or making a request only to be told that you’ve actually used up all requests for the current 3-hour period.
Edit: I actually have another one. Provide an option to download chats into a pdf format, just in case you found a particular chat interesting.
