I know I said I'd leave this thread.. but am I missing something about
the meaning people are associating with "retained mode UI"?

"a r"'s comment:

- responsive UI (retained-mode canvas etc),

Did seem a little odd to me. We have a canvas (ok, we don't call it
that, but it is). And by definition, the rendering model of a canvas is
retained. You put objects on it, they stay. (As opposed to a painting
API where we draw things continuously, and have to repaint when windows
cover regions and then become exposed again.

The latter is how X11 / GTK works, and in essence gschem implements a
retained canvas on top of it. There are some bugs of course.. the
occasional dropped cue or grip handle which would be VERY good to fix
for a professional look.


Did you perhaps mean to save the current session of open files etc.. on
exit?

(Like programs like ISE webpack and perhaps other tools use?). Spookily,
Peter B was suggesting this to me on IRC the other day, and we dug out
some protocol specs for the X11 session management. It might happen.
