Easy way to reuse a javascript transform

Would it be possible or desirable to have custom javascript transforms to be selected as easily as the built-in transforms, with docs for reminders and all?

If so, would you consider having web page where these would be downloaded?

It is on the wishlist to have a way where people can easily build up a library of Javascript (and perhaps other) transforms. We’re also happy for people to share useful Javascript transforms on this forum. A formal way to share between people online is a much bigger ask though. It might be a possibility later on.
