I’d like to make this an exhaustive article but I don’t have the time at the moment so I’ll just point out the lack of boolean operators in Mail.app under Lion. Mail.app used to support boolean operators but like other features those seem to have disappeared. Replaced with a prettier but less functional interface.
Mail.app 5.2, the version on Mac OS X Lion (10.7), is disappointing. It works much better with Micro$oft Exchange than the old version, i.e. it doesn’t crash 20 times a day and that’s a good thing.
However, the search is very disappointing. The interface is neat with the new auto-tokenizing feature but, there doesn’t seem to be any support for boolean operators or nesting so it’s still about as useless as before.
Constantly Underwhelmed
