hello @wihiker,
kiss solution: once your computer runs reliably and! you made a backup copy of the file, just stretch the ‘undo function’, normally it’s 100 steps backwards? just delete or change cell content as you like, undo will bring it back,
i know it’s not exactly what you asked for, but working ‘out of the box’, and quite handy,
only shortcoming i see: you have a fixed sequence to roll back and forward,
P.S. ‘solved marks’ and ‘likes’ welcome,
click the grey circled hook - ✓ - top left to the answer to turn it green if the problem is solved,
click the “^” above it if you ‘like’ the answer,
“v” if you don’t,
do not! use ‘answer’ to add info to your question, either edit the question or add a comment,
‘answer’ only if you found a solution yourself …
