Display all tags in sidebar in Finder

Hi.

In the Sidebar of Finder on Mavericks I can see that some of the Tags that I have created are displayed ... up to a maximum of 7 tags (from what I can see). I have about 30 tags so far. Then I can see an "All Tags" link that shows the rest of the tags when I click it.

How can I set the default to display all tags all of the time in the sidebar?
