I don't have an example handy but IIRC then PlusTools used drag and drop 
for regular browsers.

You just realized one of the things that I really wanted to address in

flexibly to standardized events in widgets. Welcome to method triggers, 
which provided a standardized way of specifying which method should fire 
in response to what event ;-)
