Thanks very much for all of that info. Definitely it will be something I will take a look at in future. For configuring "Search the internet" and "Open format externally" plugins it is a fairly complex array expression that would need a big multi-line edit area so I'll stick with how they are for now. Definitely would be nicer in future for consistency to configure it within the plugin though like you managed to.
