Hi Harsh:

I´ll try to...

First time, I did check my pics collection to recognize faces some days ago.

This exploring phase took more than one day...

The program found some hundreds of potential "faces" (or even
structures) potentially similiar to faces.

Sometimes, I did mistakes in acepting or rejecting faces.

Of course, digikam offers an option re-check again. But this is
time-consuming. And there is no certanity to click right if "face" or
"not face", the second time…

My thought is to keep some clicks in spare, so one can correct a click,
if necessary. This is, the idea of UNDO, basically.

I´m no programmer, unfortunately. And I could imagine, there should be
several different solution pathes.

Maybe just some type of cache, collecting the last ten or twenty clicks,
and, if necessary, just UNDO the last one.

thuiese "clicks" could be organized in a subsequent series of events,
the newewst one replacing the one before

n     ->     n-1 (newest)
n-1     ->     n-2
n-2     ->     n-2
n-3     ->     n-2

...    ->    ...

n-19     ->     n-20 8oldest, just one step before erasing)

hope I could make my idea somewaht clearer?

Thank you for taking care of!!
