Hello,

I add the stereographic projection.
By itself this is simple, the most of the work was to integrate the new option to the program.

It is automatically selected when you click the "Show all sky" button.
It is also possible to select Stereographic in Setup / Chart,coordinates / Projection.
The Default button set it for field number 7,8,9
I not recommend it for field number 10 because it not allow to show the full sky at once, by definition the point opposed to the map center is projected to infinity.

You can try it by installing the version 4.3-5009 from https://vega.ap-i.net/pub/skychart/daily_build/
