Is it possible to disable / hide the “No Folder”?
Not that i know. This is also a client side item which is not something which this project maintains.
You can collapse the folders (by clicking on the down arrow) that should hide it.
Disabling the folder is not possible because folders are a way to organize your vault items (including the shared items). All entries not put into one will automatically be put in the “No folder” category but you could filter them not only by organization or collection but also by their folder.
Thank you for the fast reply!
