Yes, there is a scripting language in there: "
Phil Jones asks if there's scripting in the OPML Editor.
Yes, of course -- it's running in Frontier, which was GPL'd in 2004. It's got the full environment, the object database, scripting, verb set, TCP support, web server, CMS, etc.
You can see lots of examples starting in the Window menu. The community functionality is implemented in dotOpml.root.
