[wp-docs] 3.4 help tabs

[Jane Wells]

Hi all. 3.4 beta 3 comes out this morning, which means RC (and string 
freeze) is right around the corner. I'll be putting together the updated 
text for the About WordPress admin screen and was hoping I might find a 
volunteer or two to whip up some help tab patches this weekend to get 
the help tabs caught up with some of the new features. Off the top of my 
head, flex headers, the previewer/customizer, and html in captions need 
to be added (also to Codex). I have someone taking screenshots of these 
for the About screen, so those will be available for the Codex soon.
