Displaying of sort key rather than (full)page names for category items would be way so handy in many situations.
One example on behalf of others: Names of people - they are being categorized with key in biographical order, so "Einstein, Albert" instead of "Albert Einstein".
I don't know which approach would be the best, possible approaches are:
- user preference
- _MAGICWORD_ for categories where we want such displaying
The latter seems most flexible to me.
