You might want to change the keyboard shortcut you use for OS X, it is currentl set to cmd-`, which is the system shortcut for changing between windows of the current application.
And since this is something I do a lot, I don't really like it that this is now taken by PasswordMaker.
Also, it would be nice if the window that pops up when you press that shortcut, responds to cmd-w or the close button, instead of only the escape key.
Finally, you might want to fix your contacts page, I tried to submit it there first, but it gave me a "page not found".
