Note that the TODO list has accumulated some cruft over the years. Some time ago I started an effort to remove outdated/undesirable entries, and I should get back to that, but for the present, please take the warning at the top to heart: 

"WARNING for Developers: Unfortunately this list does not contain all the information necessary for someone to start coding a feature. Some of these items might have become unnecessary since they were added --- others might be desirable but the implementation might be unclear. When selecting items listed below, be prepared to first discuss the value of the feature. Do not assume that you can select one, code it and then expect it to be committed. "
