Sounds like a good idea.

I can see that my offering is very narrow in it's scope. It maybe
solves a small problem when there's actually a somewhat bigger problem
to solve.

However, I know zilch about the style stuff (and I don't want to know
about it, yuk!) so someone else can think about implementing your
suggestion.

Cheers,

Mark
