What is driving you toward needing target import as a solution for your sequences?
Pure laziness Ken. It's actually not a necessity. I'm not a programmer but I can understand what you're saying about the variability of export files from skytools.
The way SGPro imports target information is fantastic already, I don't mean to complain. At this point in time, I'm lucky if I get any targets after spending a night out, I'm brand new to this hobby and still figuring out which software to combine.
As soon as I tried SGPro I wanted to build my other software around it, as this software is easy to use, intuitive, automated, well laid out, and the plate solving works amazing. I threw a bunch of random images at it from previous nights out, and it solved every one. This software is really great.
