First screenshot, whoo!
A good deal of stuff works. A gooder deal of stuff doesn't work yet. Here we see the heddle table (upper left) with some colors and groups (the repetition brackets above the table) the tie-up table (the matrix of checkboxen on the upper right) and the pedal (or treadle) table with the gray boxes and the grouping drawn over row headers. That info-less black box is the result of a null pointer exception; as in, not what I wanted. That will work soon, though.
Then some menus, some tool bar thingys, save / load file functionality, and we'll have a beta version. Or something.
Woo, geek out! Look out! Hoo! Hot!
