Support Nested Conversations Within a Project

What feature would you like to see?

I would like to suggest adding one level of nested conversations within a project.

Currently, a project can only contain a flat list of conversations. For long-term development projects, this becomes difficult to organize as the number of conversations grows.

It would be very helpful if each conversation could contain child conversations (one level is enough). For example:

Project
├── Architecture
│ ├── API Design
│ ├── Database
│ └── Frontend
├── Testing
│ ├── Unit Tests
│ └── E2E Tests

This would make it much easier to organize large projects while keeping related discussions together. I think supporting just one level of nested conversations would be sufficient and would avoid making the UI too complex.

A single level of nesting would provide most of the benefits without adding unnecessary complexity.

Thank you for considering this feature.
