I am very pleased with Maple (Pro). Especially that it is so fast, even on a slow machine.
I do not want another Word, so I hope the developers keep in mind - at all times - that the simplicity of the program is very important. If it gets much bigger or more complicated, I can just switch to a ore "sofisticated" program. So please keep it simple!
That doesn't mean, however, that there is no room for improvements.
As another writer asked that the links should be relative and not fixed to the harddisk. This should also go for links to documents.
Quark, for instance, has a function "Collect for output" which saves all connected files together with the file itself in a new folder. Easy to put the whole ting on a memory stick or CD.
Another thing, I do translations, and want two documents (or document panes) next to each other, maybe each with a different background. It would be nice to save the original and the translation in the same document.
