Feature apidoc - small updates

Hello Mates,

Here is some more documentation. At this point, I am out of what I can document because most other stuff is either jQueryUI based stuff (Which I do not use) or it is something I have not touched so far. Yet, I would like to ask which part should I create documentation for, next?

Also, I would love to have some feedback about how this is coming up. Do you want some changes in this? 

Regards
