I think you cannot "upgrade" Cells-Gtk, I think you have to make a giant leap for guikind and call it Cells-Gtk3 (or 4, I actually forget if I am at Cells3 or 4, the good thing being I do not think about Cells anymore (tho every 4-8 months I run into a solid bug (another reason to, um, upgrade))). Cells-Gtk3 will be an interestingly big job since I /think/ you will be getting into a user-queue handler that knows about Gtk, but as did Cells-Gtk Classic you can start by mimicking Celtk.

I knew it wouldn't just be a case of moving the asd files around but perhaps I was still underestimating the task. Here's the problems I've come accross so far.

1) def-c-output seems to be called defobserver now. Is there any semantic differences between the two?

2) make-instance 'family now requires an :fm-parent

My approach until now has been to update the cells that cells-gtk uses, then load-system, fix errors, load-system....

I'm just communicating this in case it elicits a nugget of insight from someone that might have attempted a similar task before.
