How to make the WebIDE pop-up moveable / draggable and custom sized?

@Gordon, what are - if there are - the specific guide lines how to name classes for plug-ins? ...multi level class definitions? ...what are the reserved prefixes?

You mean what CSS classes should be? There aren't any really - I'd just prefix it with the plugin name.

As for plugins, again - not really, as long as the class name matches the filename (without capitalisation). It'd help if it was relatively obvious from the filename what the plugin did though!
