Sorry I have less time and I didn't touch factorio for long time. So I couldn't fix earlier the problem with the icon.
I also added github url and changed visibility to public to give you the possibility to help. So if you have bugfix you can help or write there the issue if you find something in the code.
I have read also the problem with upgrade and downgrade plane.
