I like the simplicity of using the regular UI from retail, it makes switching back and forth from Classic/TBC to retail streamlined, there's 2 projects that look abandoned that offered a solution. I was hoping someone could please update them or tell me which code to change to update it for TBC. Thanks for your help.
