Yeah, just figure out the OSD weirdness and then create a ticket.
I haven't tried running this myself but just looking at the code
it looks like the changes to things outside the filter are minimal.
The formatting needs a little bit of work "if(" should be "if (",
we indent four spaces not two, but otherwise it looks good.
