Labels X 1.5
Unsanity folks are pretty busy: An update to one of my favorite Haxies, LabelsX, has been released today.
I used Finder labels a lot in pre-X times, and I missed them as much when I switched to OS X. But thankfully, Unsanity brought them back.
This version adds (amongst other improvements) the option to display a Labels submenu in Finder's File menu. This submenu also (and above all, IMO) allows you to use key equivalents to set labels, a feature I was waiting for. Thanks Slava!
Also labels are now displayed in Open and Save dialogs, in all applications, and there's a new command-line tool to set labels from Terminal or from shell scripts.
