I suggest improving the ChatGPT app sidebar:
Add a toggle to fully expand/collapse the “Projects” section, for example similar to how pages expand in Notion’s sidebar. Currently, long project lists are hard to manage (you need to click on the three dots “See more”).
Allow adding/removing Projects and Chats from “Favourites” manually. This gives users more control over what stays pinned.
These small usability improvements would make ChatGPT more comfortable for users who manage many projects and chats. Thanks!
