When I encounter a split-index (A-Z) page it can be quite frustrating if I don't know the first letter of what I'm searching for. I want to use my browser find! For example, tonight I wanted to look at all the functions that END in "Window" in the Chart package -- no luck:
Therefore I propose that even when generating the "A-Z" individual pages that there also be an "All" option for the single-page version. Attached is a patch against haddock's HEAD (darcs get http://code.haskell.org/haddock/ right?) that implements this behavior. As an example, here is FGL's documentation built with the patched haddock:
The great thing about hackage being centralized is that if people are happy with this fix it can be widely deployed where it counts, and quickly!

P.S. At the other end of the spectrum, when considering a central index for all of hackage (as in the below ticket) maybe it would be necessary to have more than 26 pages, I.e. Aa-Am | An-Az or whatever.
