I’ve made a couple of requests in the forums and several others have too. I’d like you to look over some of these things and implement a few of them. Personally the rescaling of the text for different orientations is my biggest gripe. The old fashioned shadow look is something that would also benefit from a bit of a tweak.
I agree that the watermarks look a little dated. We can look at tweaking that feature at some point in the future.
