When we enter a tag and select several topics, by clicking on the bulk action button and pressing the “Remove Tags” button, all the tags of the selected topics will be deleted. This action removes all tags from the topics without any warning. When the threads have other useful tags, this action is harmful and irreversible.
It is better to have another key next to it that only removes the current tag (or a list of tags) from the topics and also a warning message for this key.
