Sorry to learn that you are retiring John: Sigil has been (is) a wonderful project and will continue to be so with Kevin and Doug.
This is one app I use nearly every day!
Anyway, I'm sure to see (read actually!) you here time to time!
Have a nice time, as you gave a lot of yours.
PS I hope there is not double post to that specific matter.
