I just posted Default Folder X version 4.0.1. Thanks to everyone that provided feedback on the functionality and the UI, tested various fixes for me, and helped sort out a few of the truly funky circumstances surrounding a couple of issues.
I’m very happy with the user interface at this point – the “old style” sidebar turned out very well (thanks for the push Warren)! The preview generator is nice and fast, even under Tiger, and performance and reliability are solid on all machines, not just on the hopped up hardware here in the office and in the original beta group
You can read the change log and download the new version on this page:
