I work on multiple projects and currently use a folder structure similar to the one shown in the attached image. I cannot put all the current projects I am working on in the main vault as that would create a mess in my root folder. I prefer to keep only a few things in my root folder, specifically the projects I am currently working on. Since I work on at least 3 to 4 projects simultaneously, I don’t like constantly moving my project folders in and around the vault, as that would break some of my Dataview links inside the notes.
My suggestion is to have an option to create an alias for the project folder that I am currently working on and place that alias project folder in the root folder. This would provide easy access to my current projects without the hassle of moving the project folder once it’s done. This method is exactly similar to system folders work.
