Celtic is coming along nicely. I actually forget where it was before, but I am pretty sure the scale, spinbox, and panedwindows are all new widgets. Not much left. Toplevels, yes, and maybe menus could be made friendlier. Of interest for aesthetic reasons is that the internals got a massive clean-up that makes me feel a lot better-- there was some weirdness in there.

As for Cells III, panedwindows were the first thing that did not play well with Cells. They insist that the widgets which will occupy a pane be fully assembled before being added to the panedwindow. Turns out Cells II made it impossible to place the "add" code anyplace guaranteed to run after all initialization, because it defers things. The good news is that I simply added a new category of operation (finalize) to the four I already had (user-notify, output, setf, and makunbound) and it Just Worked. Which I usually take as a Good Sign, but it still makes me nervous to think I have made "after" into something tricky. :)
