Updating the download right this second.
New this version, a rudimentary beginning of the Nugget Editor. Also a handful of random fixes. It's no where near ready to use really, you can't even load or save things.. but I thought you guys might want to mess around with what I have so far.
I wrote up a little about how the editor and Nuggets work on my dev blog: http://robotlovekitty.blogspot.com/2011/11/tiny-plumbers-nugget-editor.html
