Currently, the quick reply popup works only with standard text messages (to my knowledge). It'd be great if, say, when someone sent a photo or other MMS, or group chat, could also use the quick reply popup. I know other message applications do this. Maybe even an option to use quick reply popup for "all messages," "standard text only," or "off." Or some more applicable set of choices on that. I switched from Handcent to Chomp. Would hope to see this in a forthcoming update.
