I think Projects need a multi-level hierarchical structure for organizing conversations.

Currently, every conversation thread sits directly under the Project. This works well for small Projects, but as a Project grows to dozens or hundreds of threads, it becomes increasingly cluttered and difficult to navigate, organize, and retrieve previous discussions.

I would like users to be able to create 3–4 levels of hierarchy within each Project, similar to folders and subfolders. For example:

Project → Module → Submodule → Conversation Thread

Ideally, users should be able to create, name, and organize these levels themselves depending on the complexity of their Project.

For example, a medical knowledge Project could be structured as:

Radiology → Neuroradiology → Brain Tumors → Glioma

This would turn Projects from a simple collection of conversations into a much more scalable long-term knowledge workspace, especially for professional, academic, and research use.
