Option to ignore render elements when working with history

[Art48]

It would be nice to be able to not havin the screen go blank when loading/"over-rendering" a previous image with different render elements.

Would it work better if we only preserve the RGB/Alpha and clean out the rest of the elements?

Best regards,

Not quite sure if I understand you right, but basically all I care about is havng the RGB/Beauty left there so I can compare better and not having all black around my render region when doing an A/B.
Jackpot woul dpropably be to have the combined render elements of both A and B in the list and jsut display black if one of A or B doesn't have the appropriate element.
