Is the request systematic or is it based on some analysis if the border ? In the later case, could ST provide some feedback on the area it found problematic (automask, border size or so one?)

However I find it tiresome having to drag the sliders (followed by much clicking!) to get the borders set correctly. Yes, I know if I load a second image stack without closing StarTools in between then it will remember the previous crop dimensions but often I will capture and process a single channel in a night.
I would certainly appreciate some more options in the crop tool, perhaps crop all borders by (n) pixels, or even the ability to type numbers in rather than drag & click sliders.
