Separate Model Preference for Side Chats

What variant of Codex are you using?

App

What feature would you like to see?

I'd like to have side chats maintain a separate default model on creation. For most side chats, I happen to want an answer to a quick question. For the main agent, I want a high-effort, smart agent.

When I create a new side chat, I want it to use the model/effort from the last side chat I had within the project, rather than inherit these from the main chat.
