If you're using the "Has No Tags" filter to help with your review, you may encounter behavior where documents disappear from your review, and take time to synch and optimize, as you're adding tags.
Why does this happen?
When you select "Has no tags" from the filter carousel, Logikcull actively applies that filter without ceasing, which can cause documents to disappear from your review set and run a "syncing and optimizing" function as soon as you make a single change.
The filter carousel is useful for quality control and quick document gathering, however the "Has No Tags" filter should be avoided when setting up a review.
What should I do instead?
The easiest way to get around this is to run a search in the search bar for tags:None
This will create a static list of documents that will not need to be dynamically updated every time you tag.
You can even save a search for tags:None and easily re-run that saved search any time you need to refresh your list of untagged documents.
