So far I find the program terrific. My only real gripe is that reference image docker.

I always have to browse back to the original image it opened - very annoying. Right now it's much better using a reference directly on the canvas so when I open it later it's there.

No zoom function with mouse or pen. Terrible!
Every time I want to take a closer look at the ref image I need to use that zoom-window-thingy. Just let me zoom into the image as I would normally on the canvas!

Cannot flip the image. These days I do it a lot since it really helps. You know, like using a mirror in the old days

Yes, we know. The original author has disappeared, and up to know we've lacked time to work on it ourselves, or volunteers to take over maintenance of it. We did plan to work on at one point, but then there were more important issues to fix. The only thing I've been able to do is make it crash less. Maybe once the scripting framework is done, it'll be easier to reimplement it.

Ah, okay. Well, for now I am using separate windows. So no big deal

The reference Image docker is a pretty good idea, just need some fleshing out. Maybe someday.
