Hi @hogi. I think it's a very good idea. Although, I could not find a way to add additional examples directly to the Scripting index. As a workaround you can create an add-in with your additional examples for these functions. You can then share this to your colleagues as well.
If you have them "collected" in one or separate files you can use this JSL Function List add-in from JMP Marketplace to find and manage all of your JSL functions and expressions.
