Maybe, we can delete the options and realy export everything (but this can be a lot of columns). I don't know what exactly is stored in `seeAlso`. And does it make any sense to export the `uniqueFields`?

Going this direction (export everything), I suggest to fix some ordering. In this way we can put everything which we think are less important (e.g. attachments, tags) in later columns. I tried to come up with a good ordering of the columns but I think my flexible approach is not always giving good results...
