This is stored in an atom for projects folders, so that when you close and re-open the explorer, everything keeps its state. I think it would be great to also save that in an atom for the projects.
I think we should create an atom openProjectState with some useful values like name, id and isCollapsed. When we update the app so support multiple projects, we can then update the atom to be a list of ProjectStates

[cguedes]

I see your idea, but I think we should implement that later once we really support having multiple projects open at the same time. For now we are only making sure we have the design ready.

[hammer]

As part of this change can we create a top-level folder called "documents", put it above exports and uploads, and put the documents under there?

[hammer]

Or if that breaks the data model, we should at least have the documents above the exports and uploads, I think.

[cguedes]

That change of having a top-level documents folder is a bit complex in terms of data model and UI logic to make it expanded (when opening a project, creating a new file, ...).

But showing the files before folders (i.e. above exports and uploads) should be very simple. We will do that in a follow-up PR.
