An update on our end.
Creating new tags while editing a card inline is supported right now (using / or \ + #).
We will be further improving the tag creation flow in a future update, so you will be able to just type # to add a tag to a card → we hope this will resolve most peoples friction surrounding tags.
But this isn’t the same as “Inline tags” – where the tags are present within the middle of the body text in display mode and are clickable / filterable. This is something we’d like to do and is now possible with the introduction of our new editor, although we currently like the clarity of having the tags separately on the bottom right of a card and are easily viewable and clickable in one place.
More thoughts are welcome!
