Hello. It would seem there must be such an option. However, I haven't found it.
Sometimes it would be convenient to see neither tagged nor labeled items* only.
And sometimes — only labeled and not tagged.
To sort them by date or otherwise.
( * Items — files and folders.)
Filter - Show (un)tagged or (un)labeled only
Re: Filter - Show (un)tagged or (un)labeled only
This works for me on Extra Column 5, if your meaning a specific column and not no tags at all
ex5:;no:ex5:?*
