I'm looking to add some advanced features for wordpress to give users better control of certain areas. There are two areas that I want to focus on right now - adding a section for the user to change out the header image. (I have a theme that does this - need to reverse-engineer it) and control image replacement on sidebars in some easier fashion than editing the html in a widget (maybe add a small wysiwyg editor in the text widget). There are other items as well, but that's a start. Please let me know if you think you could help with these and other items.
