Glad you like the new features Robert
Hopefully there will be no serious issues found over the next few days and then I'll publically release 2.5.7. I do think its a big leap forward from the last version.
By the way, have you tried the bulk photo import yet? I rewrote it completely to be much more efficient. One windows user said he imported 200 pics in 15 seconds. I haven't tested it extensively on the mac end, so let me know.
