This document contains a list of the problems for which feature requests have been made. Linked problem pages contain the document of the problem and their relevant solutions. Obviously, we want to keep HTML as simple as possible. That means not everyone will get what they want. Having good documentation for the problems at hand will help all of us work out what is most important.
If you want to add a feature request, you should probably start by coping the Problem Solving template page on a new page and fill as much information as you can.
