Can we render HTML and set default models and agents in Dust?

Hello, couple of requests, hope you can look into them: 1- is it possible to add a feature where html is directly rendable in dust chat? that would be a great addition, similar to what claude desktop and chatgpt do 2- Is it possible to add the ability to set the default model for the default dust agent? That would be great. 3- Setting an agent as the default agent in dust, instead of the native dust agent, is that possible? Thank you very much!
