Script Download

Wow, that's a lot of stuff, nice work!
If you could add a link to this forum thread in the YouTube video description, then people can find the script download from the video too.

ah, did you develop these on Windows? The script file names are case-sensitive on Linux and Mac.
So if the script file name is "PrintInfo.rs", then in the layout.json file it should also be "PrintInfo.rs", not "printInfo.rs".

ImageNameByFile is a great idea, you could set that to run after dropping images into the scene... much better than the default names of 'image3', 'image4' etc

One thing that would make it easier for people when they first try these, is to set the minBodies, minFixtures etc values in layout.json. This will make the menu items grayed out for scripts that cannot be used when the appropriate items are not selected. Search the help for "minBodies" to find the topic about that, and see the layout.json file of the default menu for some usage examples (eg. add joint requires two bodies to be selected).

By the way, a few things to point out:
- there are dr(float) and rd(float) global functions to convert between degrees and radians
- shape::getRadius() is implemented now
- spelling should be 'grow', not 'glow'

I like how you have grouped item types into an 'Element' class for generic operations... awesome!

Embarrassing spelling errors.
Was fixed whatnot.
