Bonsai 2.8 - IronPython Python Transform editor not opening

[vncntprvst]

Hi,
I'm updating some workflows from 2.6 to 2.8. The Python Transform operator from the IronPython library had to be updated, so I'm copy-pasting the former Python code to the new operator. Strangely, the editor does not pop up when double-clicking on the operator. Have others observed that behavior? The Script field does not have a drop-down menu to visualize the script either, so it's not convenient to write code in there.
Thanks

Have you installed the corresponding Design package?

Ha, no. My bad. Forgot about this :)
It works now.
Thank you Bruno!
