Doc change suggestion - prototype links in menu

[Edit below]
  May I suggest that, useful as they are, the CI 3.0 docs need to include a menu link to the function prototypes?

For example, in the docs page for form validation:

CI_user_guide_3.0/libraries/form_validation.html

  The viewer must scroll down 49 (forty nine) screen pages to reach the top of the list of function prototypes (your mileage may vary depending on your screen resolution).

  The developer must then continue to scroll down to locate the one function in which they're interested.

  Can we instead add menu choices on the left column which, at a minimum. link to the top of the prototype list on a given page?  Ideally, this menu list would show a link to every prototype on the page, but at least allow us to jump to the first prototype listed.

Not a flame, just a suggestion to make the docs more usable.

[Edit] Ok, I found the link to the top of the prototype list, so that is one item addressed already.
The secondary point still stands, add menu links to each prototype. [/Edit]
