Removing some animation, increasing speed.

- The animation that made the labels move is kind of jarring.
- More saccades? Distraction, akin to magicians semi circle hand
  gesture?
- Need this to be quick, and reading to start asap.
- I like some animation and with .2 you could barely see it.
- .3 seemed too slow, .25 seems to be a happy medium.
Maximum z-index.

- This really should have always been there, but specifically fixes an
  issue with the atom-color-highlight package which I really like.
Updating README.md with keywords.
