It's a little harder for a pixel-editing programs, because many actions are
actually one-way operations upon large collections of data.
For example, how would you un-do a blur? If you perform the corresponding
sharpen you're actually doing two discrete operations, and the resulting
data will almost certainly differ from the original data.
A pixel-processing program is different from a word-processing program or
vector-drawing program. That's why the History Panel there saves your
preferred number of previous states on disk, and reverts to a stored state
when desired.
