Comment on Measuring Cup

I've been looking for a good recipe manager... thus far, none I've run across (commercial or free) qualify as anything above "good", but this one takes the cake thus far.
The interface is compact and functional, and it has many logical features that are just plain absent from EVERY other recipe program I've come across (sub-recipes, grouping ingredients, and numbering/grouping instructions, to name a few). I've fiddled with Yum, tried YummySoup, and looked at/tested a dozen or so others.
This one is the best I've found by a large enough margin to ditch everything else completely. And look! Free! All it could use is a couple other features, especially in the searching and displaying departments, and it'd beat out every other app I've run across in every way.
