I see. I wish to do some trending, graphing only. I saw some photos of
Ceres with dual screens mono/colour, that I plan to mimic with SW.
While SW remains for invert.
Instead of Gadgets, we can support simple pop-up menus, like I saw with
Lilith, Mensa. That may still comfortably fit within 1MB. Just ideas.

Yes, faster, I see. I stretch with parameter 1-bit (no stretch)
4-bit stretch), that took me some time to understand. I got some speed
back with optimised scroll, though I loose some with font
I do not need to rebuild system so far (which may be of little or
no benefit), may require a change in time to get on compatible Display
interface with Ceres and yours, too.
