@Jeff,
What do you think about this?

It’s a nice proposal, and well-presented. I like the details, and the later clarifications. One thing that pops into my head is that having convenient framebuffer access could be nice. But I was thinking of making some changes regarding how graphics are handled in a few places… (Currently, the Function Plot view, for example, does not use, in the main, offscreen buffers. I wrote this code for the HP 39gII where memory is extremely limited. With the much greater memory resources of the HP Prime, offscreen buffers are more appropriate. As a programmer, perhaps you can appreciate the care needed to do things like drawing and undrawing the tangent lines, marching ants, and signed area display in the Function app’s plot view — without using offscreen buffers… [and without redrawing the plotted functions — using just the pixels onscreen {the tangent line only know the value and slope for the function at where the tracing cursor is; the marching ants only know the pixel coordinates of the cursor; changing the signed area by one column involves computing the upper and lower bounds at one X value}].)
