I'm sorry if this is duplicative, but I have been travelling. I just wanted to comment on the "recenter every xxx" request since the wording of the poll sort of implies it might not be too important. I thought I would explain why this would be extremely useful to me. I am using a mount that does not require guiding for modest focal lengths, a 10Micron GM1000HPS. I am very thankful that SGP implements the direct mount guider to allow my subs to be dithered by SGP. That is great!. The problem is that while the mount is good enough to permit 20 min or longer subs with round stars, over the course of a long imaging session, say 8 hours, there is drift. On a recent image collection I had about an 8% drift on one axis, so I had to crop 8%. Normally this is not a huge deal, but in this case given my image scale and the size of the target I had framed it very precisely and this amount of cropping was almost enough to harm the image. There is a way to get around this, but it is not very convenient and since it duplicates data it is error prone. I break the imaging into multiple identical targets that are about 2 hours long and that way I can force SGP to recenter as each target starts. While this is certainly useable, it is hardly ideal. There may well be far more important features, but since on the surface it seems this should not be too hard given that SGP already has like auto refocus that interrupt imaging on a time/frame count basis to run a routine, I thought I explain why I (and I'm sure others using high end mounts) would appreciate this facility.
