All these are good examples. I would also like to add some:
- rules for free use of images of copyrighted product packaging (free use of book/CD/DVD covers, etc might be included here or separate)
- some kind of clear rules for to what extent one has to rework a work to create a new, derivative work (at which point do new, separate rights for derivative works rise? this would help a bit with museums and archives claiming copyright on photos etc of their contents, like The Israel Museum claiming copyright on their images of Dead Sea Scrolls or The Smithsonian Institute on some high-quality, digitally cleansed images)
- clear rules on what constitutes mass production and hence is not covered by copyright (mostly, this concerns product design and architecture)
- I'd very much like an international agreement to put things like money, postage stamps, etc entirely out of copyright
- some international agreement on more specific issues concerning countries with "interrupted history" (like the whole former Socialist block, but there are certainly many other examples): the status of works produced under occupation by state agencies, or by the juridical persons who ceased to exist (can author of an encyclopedia article published in 1939 claim any rights if all rights originally belonged to the publisher discontinued in 1940? which juridical persons can or can't claim to inherit the rights of such a publisher?)
- the terms for media channels could be shorter than for other kinds of works (most media outlets do not earn money from their editions published 30 years ago, but historical media is an important part of a society's public memory)
