On 5, I don't see how it's an Adobe problem when Adobe handles spaces fine. E.g. copy and paste text from a PDF works on a computer. Although it doesn't affect me since I always use sketch instead of annotate, but I can see why it would annoy others.

On 6, I didn't know that about paper mode, page mode, comic mode and scrolling mode. So now, I would agree with you on this.

However, I still don't see the difference between zoom by 2 points and selection zoom. You say that zoom by 2 points zooms, while selection zoom changes the page size. But how are these different? To me they seem to do the same thing.

As for auto-crop. I'm still not sure what that number does. Regardless of whether it has white margins, auto-crop correctly removes all margins. So it seems to always work, without needing to enter a number. On the other hand, auto-detect margin never works (although that doesn't bother me, because auto-crop works).

Can you explain what the DRM settings do? Thanks.
