Tom, thank you for your interest in Core Animator. Unfortunately, the Mac app is nearing the end of its run, so (unless something changes) these features will likely not be added. We will be focusing on the iPad version in the future and can't guarantee that these will be added for the Mac version. To answer your questions: No, there is no snap-to-grid. Yes, you can change an image with an ease/tween: Select an image element at a point in time and choose a new ‘Image Source’ on the right hand panel Yes, we did remove group fx. Apparently we didn’t scrub it from the documentation - sorry for the confusion!
