I have many different projects. Many of them relate to each other in some way, either because they’re under the same company or the same topic or the same overarching goal.
Often it’s not feasible to put these projects in a monorepo or organize them together efficiently on the file system. It would be very helpful and handy to be able to create folders in the sidebar and put many projects in one folder to organize them that way.
Welcome to the dev community 
ahh you are talking about the desktop app. Are symlinks allowed?
I’m sure symlinks would work fine, same with creating folders and putting the projects in there (what I do now for the most part), but that’s not really a good solution IMO. What I’m talking about is not really a permanent structure, rather something that changes frequently, like having a category for active work, one for a specific client, one for a general topic which will be moved or merged with another one later, etc.
Also, when you got multiple projects in one folder, each thread’s workspace is that entire folder by default, not the project it’s targeted to work on, so with each new thread I have to explicitly say which repo to work in.
I hope this makes the problem the feature request is aiming for a bit clearer 
I was thinking more like this:
- project A
- project B
- project C
- dynamic project A << use this in codex
-- symlink to pA
-- symlink to pB
Just show it to codex and tell it to make a new project skill which lists all projects so you can select A,G, ZZ1
I mean your idea is good. I use vs code and I add folders to the workspace .. so I know exactly what you are talking about
For example on this here.. where I add functionality to the programming language with an extension (king) and then when I want to add that functionality to a vs code extension (coder) it makes sense to have both in the same folder… and then there is also the app that caused the whole change…
