Navigate control is very slow

[joeblew99]

On android the navigate control , when pressed, delays for 1 or 2 seconds, before opening up a list from which the user can see the page names.

I like the way it works because it's not using side bars and other semi confusing GUI techniques.
But the 1 or 2 second delay made me think something was broken, and it's really disconcerting.
