Can you fix the “no folder” thing? I find it very confusing. The items that are not put in any folder should generally and automatically be in “all items”, no in the “no folder” folder (which doesn’t even exist. Only the folders that we create should appear.
I don’t know about the others but I find it very confusing.
Not sure if this changed in between but in my case the folder “No Folder” exists. I didn´t created at any time so he comes from the system.
“All Items” is not a folder it shows you all items you have access too (like the name said it), so it´s a view.
Maybe a name change from “No Folder” to “Default Folder” would make it a bit more clear.
