It would be nice to be able to set a default "folder-level" character. While still allowing it to be changed in individual chats in the folder.
For example, say I have a series of questions I'd like to ask about a server-side project I'm working on. And I created a software developer character that focuses more on the specific tech stack of my project. And, my questions are regarding different areas and tend to become long discussions so I prefer to ask them in separate chats instead of jamming them all into one. It would be nice to be able to set the character at the folder level so that when creating a new chat in that folder, it uses that character by default.
