We've successfully added a button to the compose toolbar using a zimlet, and it works great. We just noticed, though, that the button doesn't show up in the detached compose window. In fact, I'm starting to suspect that our zimlet JS is not even being run in the detached compose window. We have some code in it that modifies ZmComposeController, to add our button, and I just can't get that to run in the popup window. Am I crazy or are the zimlets not loaded as part of that detached compose page?
