Add support for more content types

e.g. tool call request, tool call response, images.

Would be nice to have a checkbox that let you toggle tool calling messages on and off for debugging/better understanding of how a tool works.

Second both of these suggestions - It would be very useful from a UX perspective if a user was able to explicitly see what tools were used, and when they failed. I find LLMs handle tool issues very gracefully which can be confusing at times in a chat interface. Displaying images directly in the chat repsonse would enable a lot of use cases.
