I agree Roskav. I wish they get the foundation right before adding features.
I would not attempt to make any client a test pilot for such features when I can't even reliably have basic features of the app such as formats arranged properly.
I have it up again now as a test while I use IDImager, and ACDSee5, and so far IDImager does things, a bit differently than others, but OK so far. MPro crashed on me a couple more times, and just wonky. its sluggish, and there is no feedback when it starts a process to let you know its working. I think the core maybe strong, but it is hurting from major clarity issues.
