Improve keyboard accessibility
Keyboard accessibility, in terms of visible keyboard focus and the keyboard accessibility of the main menu, doesn't appear to be that good. You have some fantastic tools for changing the look of the content and for in page navigation but it is not possible for those who are unable or prefer not to use a mouse to access these features.

I remember being able to bring up a search box by typing / (slash) but that seems to have been removed with the update. There is a search box in the corner but it isn't automatically activated with / like it should be.
