gambard@ can you chat with mardini@ and martijnb@ to see if there are any tweaks we can make to this in M69, such as speeding up the animation, etc?

Post M69, we should give this more attention.

There was some discussion at the UX implementation review, though not enough to come to a decision. 

The main point was that the Fakebox to omnibox animation feels a little slow, though this may be constrained by the keyboard speed. When the text saying Search or type URL"  jumps to the left, it also looks a bit jarring since it jumps while the keyboard animates upward.

One possible solution that ainslie@ mentioned was to just remove the "Search or type URL" once the user taps on fakebox. This may be problematic, though, since that text prompt may help users understand the functionality of the omnibox.

Gauthier and Martijn spent some time on this and improved it a bit. Martijn will be sending videos to Alex to get feedback. Marking as Started since it's being actively worked on.
