Thx for the details. Especially 2) was very helpful as i had a wrong imagination about "built in python" and i was wondering that nothing worked as i didnt installed a python interpreter in my VM. I wasnt aware that there is a python interpreter as exe coming along with sigil which needs to be brought in here by the Auto button.
So i will see to change my plugins to be able to run without having the need to install a seperate python interpreter
Unfortunetly, the sigil-python3.exe cant run alone so i as a deverloper needs to have it installed and due the already existing 2.7 plugin i need to have the 2.7 interpreter installed as well.
Not an ideal sitiuation...
Nevertheless
