Re: QT GUI Time Raster Sink - missing MSG port

Hi Vittorio,

what you're doing is sending a feature request – and that's more than fine! It's actually
*welcome*! Because we need to keep track of these, prioritize and implement things at some
point, we actually connect these in the issue tracker. If you go to [1], log in, click on
"New issue", and then select "Feature Request", you do the hardest part of that thing –
and your email's text is good enough, I'd say, so just copy and paste it into there :)

Thank you!
Marcus
