Allow me to do the following: instead of fixed depth of projects, turn it into a tree with more depth. Let’s say 4. Then remove projects 
Reasons:
- Remove projects, it is restricted on UI. For some reason, Deep research option is only available outside of projects. I have to do it outside and then move the chat inside a project.
- Right now, to find a relevant thread inside a project, I need to find it from a sorted by use date list of threads. It’s cumbersome, time-consuming and doesn’t automatically club similar threads of “same” project.
- By allowing to club threads into a tree structure, I can have full control on my threads’ management. AND it is much more convenient.
- remove projects because if you do this, you no longer really need projects. Its just a name holder.
(okay removing project was a bait, but tree style thread management will make my and, I would assume, others experience on UI much much better)
Also, please allow converting temporary chats to permanent.
