This workaround makes the list of notebooks or tags look a bit too crouded and messy for me, i whould need another search engine to search through it.
I have tags 'Novel', 'David' and 'Sara' which are nested:
Novel
David
Sara
And in windows app I can click on 'Novel' tag and list all notes with nested tag. My question is how I can search through all notes related to the Novel, i.e. tagged with 'Novel', 'David' or 'Sara' without adding tag 'Novell' to all 'David' and 'Sara' tagged notes too.
