Selective History?

Recommended Posts

Poo, is it even possible, as in future releases?

The problem, I think, is that each action is cumulative. It builds on what has been done before to create what you see. You can't undo one action without doing the seven that came after it, because the other seven depend on that first one.

For instance, if you duplicate a layer, ran a Gaussian blur, changed the blending mode, and then merged the layer down, you can't just undo the duplication - because the merge action depended on the duplication action that came before.

I can imagine that a workaround might be possible, but I can't even imagine how difficult it would be to code. You'd have to put exceptions in the undo command for every other effect and tool...there would be riots in the plugin section...cats and dogs living together, it'd be crazy!

In thinking about it, I can't even think of a single program that allows you to do what you're suggesting. Microsoft programs, Adobe programs...

I would like to see history saved with the .PDN file, though, at least until it's cleared...


The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.
