I just posted an update to Maildrop, it has a couple of bug fixes along with some new features.

• Can now create leads in addition to contacts from the add email page, the add lead/contact buttons are now much more obvious.
• The Add Email dialog is reset between emails, it no longer defaults to the last email's selections.
• Malformed search error with email addresses containing dashes is fixed.
• New menu item to reinstall the scripts (under help), and error reporting when the script install fails.
• New application icon and updated help.

If you have an earlier version of Maildrop, it'll auto update the next time you start, or pick check for updates from the help menu.

This I think was pretty much everything that people commented one, other than a couple of Mail specific issues, which i'll be looking into next.

I also got around to putting together a single page that details all the Saleforce.com/OSX tools I've built, see http://www.pocketsoap.com/osx/
