<< "I miss being able to have objects like clickable frames follow the scrollable background." >>
Hello Rolf and Klaus,
This can be done in Opus. Just insert the frames/objects also, into the main frame. They must be "insert into" and part of the Frame. See the attached IMP on what Fred was explaining to do. I have supplied a crude example.
<< "I sometimes use maps in my publications and have to scale them down to make everything appear on the screen, which sometimes leads to blurred and unreadably small text." >>
Also in regards to "scaled down maps", if the above scrollable image is not suitable you can use a magnifying effect in Opus. i.e. like a magnifying glass that is dragged over the page.
