We've heard a lot of big things about leopard, but for me the experience lies in the details. One thing I hope for is the ability (à la windows) to only empty the Trash of certain things - permanently delete one in five things in the trash. Unified GUI is another common request (we've now heard something about black gloss) Boolean search in spotlight (to make it faster) MSN integration in iChat is unlikely to say the least, but would be great. Numbers (iWork spreadsheet) looks promising. Maybe thats not so minor. Integration with iPhone Quicktime to include features from VLC player, as it just doesn't support enough codecs. I don't want three video players. What minor features are you looking for?
