Currently, trying to edit a HUD (most of which use touch controls) works like this: Save script in the HUD button you're editing. Try to touch the button. Remember for the umpteenth time that you can't touch a HUD object while in the build menu. Close build menu. Touch button to test script. It's broken. Reopen the edit window and repeat... Turns out that the new skinning support and documentation enabled me to find out, un under 5 minutes, how to add a Touch function to the pie menu by copying the XML code from another file. While I enjoy my newfound power (Woo!), this should really be default behavior in the main client, so I'm sending in the edited XML file as a patch.
