I can get by without these because there are simple alternatives.
The suggestion that I miss most of all - and REALLY wish you would implement - is https://bbs.zwoastro.com/d/25221-asiair-duo-cameras-guide-sensor-field
It can't be that hard, and it would provide something which is not possible with off-axis guide cameras.
All those using DUO cameras would be overjoyed, especially those using longer focal length scopes - and there are quite a few. I know small refractors are very popular in China but elsewhere there are many using large Newtonians or 9" - 11" SCTs, and even a fellow using a 350mm CFF f/15 cassegrain.
