This is a cool idea, but it seems to have some bugs because I can only open some widgets, not all.
Also, I MUCH prefer the combo WCode/Widget Creator (www.widgetfactor.com) which I downloaded a while ago even though it is shareware. I find their package well worth the price because it lets me do more things than widget maker. For example, it makes use of drag and drop to change widget files which is really cool and practical. Most importantly, their interface is "prettier" and allows me to access every single file, including images, that compose my widget. Also it includes widget creator which offers graphic templates to speed me along.
Sorry but my choice between the two is made! :)
