The first question:
I use MOI 3, when i call the Node Editor via "F8" Key
i get this Error Message. See attached picture.

Found "delaunator.js" and copied it in a different Folder
solve this. Can start the Node Editor then without any Error.

Do anyone know what cause this Error and have a Solution,
apart from copy the File to different Folder.

Know anyone what "delaunator.js" is for. Maybe i would
never need it, because i never use this Feature.


The second question:
Instead starting the Node Editor via the "F8" key
i would like starting them by clicking on a Icon or Text Button.
Can somone tell me how to do that.

thank you in advance
