A handy feature in Workflowy – when a search begins with a tag symbol – # or @ – a list of matching tags pops up that filters as you type.
For example – search for “#f” and you’ll see a list of all tags that start with “#f”. Type another character such as “#fa” and the list filters down to just tags that begin with “#fa”. This is very fast and easy to use.
It is much faster to use than the Tag List pane in Dynalist.
Please consider this as a feature request.
