This style is effectively dead, as Tumblr has reverted the action bar to classic. Unless they update it again, or X-kit adds a way to replicate this format, it'll stay inactive.
Thanks for using my style :)
Wanted to see if I could fix it. Debatably did.
Notes
Some pages don't work but I'll update with time. :) [note: lol]
