I don't know the technical answers, but there is a more practical answer. Jon would have to buy the Xenforo add-in for each of those abilities - if it exists - and his budget is not that big. The advent of Google's AI, Gemini, puts the squeeze on LOTS of help sites including this one. I understand that Xenforo has lots of add-in options, but none of them are free and Jon really WOULD like to make a profit now and then. He has done a lot for our security issues and has implemented many nice visual abilities, but he has lots of expenses to consider. For example, he has retained technical posts from a couple of decades ago. Contemplate the amount of storage space needed at the hosting site for 20 years worth of posts.
