Thanks Rick, good to hear an update here. I look forward to seeing where things are moving.
Like some of the other folks expressing their opinions here, personally I am most interested in a really robust and reliable set of basic image operations with a good UI to them operating on sets of images. That's actually what gives me the most 'speed', and I almost only use colour, crop + sharpen and the occasional localised layer

Bugs like deadlocks are still there and really can come at inconvenient times, too.
I do worry that things like OpenCL and GPU could be a distraction, though I note that you don't say this is the only thing being worked on. But I do wonder if there could be bigger gains in image operations (for the same effort) by, for example, ensuring more of the image processing is previewed on the screen-resolution images (and which would help all users, including those on very modest systems) Of course I only hypothesise as I don't know about the ASP internals, but sometimes I wonder if Bibble 4 feels faster for these reasons.
I'd be interested in beta testing on Linux, though this is probably not the place to ask.
Thanks again, and I look forward to seeing the progress in the other non-GPU areas! Fingers crossed.
