I inquired about doing this myself a while ago. I’d still do it if I need to, but it occurred to me that maybe the feature has broader appeal. Besides, for somebody that really knows the code inside and out, this would be much easier;-). So: Sometimes it would be useful if TinyG would sent out something when it has done the commands it has received. I would use this to take a picture with the camera for precise optical alignment.
Thank you!
