Created attachment 42955 [details] mockup Let's say that you have an image that is stretched to be bigger than the slide (because you simply want to resize it, not bother with cropping etc) or you're just a bit sloppy with alignment or something; currently, the image (or object) will be shown on top of the slide boundaries. Instead, the slide boundaries should be shown on top of the image. This could be accomplished by having a always-on-top slide border and/or a semi-transparent always-on-top black mask around the slides, so that objects that are outside the slide get "faded out". This would be a good visual cue. Attached is a mockup that explains better than I do.

Thanks for new idea. I agree that it is great improvement. Currently we can see slide boundaries through picture only if before this picture was less than slide. But often picture is initially bigger than slide. And we need do additional work: first change picture to bee too small, and then adjust as needed.
