Knowing that the WP 34S is finished and everything: This sounds so interesting!

Any chance of seeing it there?

The same question goes for the WP 43S naturally...

It's all a matter of space. The WP 31S is stripped down from the WP 34S - in particular, it's not user-programmable and supports far less registers. This gave us 'lots' of free space we used for implementing UNDO (which in fact recalls a copy of all registers). There is definitly NO chance anybody will see this in the WP 34S for the reasons stated. Sorry.

For the WP 43S, OTOH, wishing may still help. I'd guess, however, that a confirmed (!) deletion of all registers won't be made revertible, nor will a confirmed deletion of a lengthy program. As stated above it's all a matter of space, and I think most users will prefer an increase of accessible data and program storage area over an increase of (inaccessible) backup space, especially on a calculator offering some I/O capabilities. Just my 20m€.
