Hi Stefan, Apologies for the delay in reply. Just wanted to let you know that we are not ignoring you -- the timing was just rough because we recently returned from an intense hackathon (see https://github.com/imagej/imagej-ops if interested) and are still catching up on the backlog. I will make an effort to reply to your questions within the next few days.
