I've been using the Lumenzia panel for a few days and I have used the TK panels for a while now. Although I have not processed many images with the Lumenzia panel yet, I am impressed with the thought process and the approach. As it is a Javascript panel, it is "smart" and is not just a set of actions. The approach to creating the masks using a B&W conversion with a curve is very clever and much more flexible than the self-intersetion method, although the Lumenzia panel also gives you the option to CMD-click on the panel to create the traditional self-intersection mask as well.
Watch the overview video and I think you will be impressed by the thought and implementation that has gone into this tool set. The ability to visualize the mask prior to applying it, and then being able to substitute a mask on the fly and mask a mask and combine the results is a huge timesaver.
Thanks for pointing this panel out Russ. I am not affiliated with the author in any way either, I just had heard about this a few months ago from the Color Theory email list and was waiting for it to come out.
