Anyway, just what is it I'm about to undo?
It would be cool to have a visible undo stack, but a good sized step in that direction would be to let me know the name of my incipient undo. Instead of "Last Action", tell me what that action is!

With Adobe programs it's know as the "History Panel".
The History Panel contains a list of several past actions. You can look back through the list, with one click you can undo several past actions.
It can be pretty handy when your experimenting with special effects.
If you haven't flattened all the objects you can also select individual items to remove them.
So, what have I missed please?
I like manifest clarity as much as possible. Let me peek into the future if only just a little bit with what I'm about to undo
Depending on your workflow, the history panel can come in very handy.
I'll use Photoshop, it makes for a pretty cut and dry demonstration. Here is an image with a number of edits applied to it.
The Edits appear in the History Panel to the right of the image. They are arranged in the order they were applied. The uppermost being the first applied and the bottom being the last one applied.
In the following image, I simply clicked the "Open" tab and undo every action applied to the image since it was opened.
I can select any tab. So with one click I can see the image at any state of Edit. And with one more click I can Redo everything I have undone.
You don't need to hit undo and redo 20 times just to remind yourself what the original image looked like.
Plus, you can revert back quickly at any time and ask yourself , am I satisfied with the changes I've made so far?
What about the changes mid-way through the process?
Is it time to re-group?
Not only is it a time saver.
Greater functionality returns benefits like higher productivity and lends itself to more creativity in the long run.In my opinion.
Not every change can be undone which adds complexity to the undo command as you don't always know what changed. In some cases multiple undos are required to correct a single change WE made. A cut for example requires two undos. One for the cut and one for the split.
Here is an example of how undo can become confusing. Especially when you just took a break.
First phase shows the lack of knowing what was undone.
- Add two callouts.
- Add text to the FIRST callout.
- Select the SECOND callout and reposition the timeline to show the second callout.
- Undo. It would be nice for the focus to change to what was undone. E.g. the first callout loses a character and gains focus. A redo shows the last character so we can see what we did.
- Add a single character to the SECOND callout
- rotate the canvas.
- Undo. Nothing happened? Actually, this is a case where multiple undos are required to undo our single action. Cut is an example. First undo undoes the cut and the second undoes the split.
So, while the Photoshop undo list (which itself has issues) would be nice. I would be happy with just having the focus change to what was undone. In the fourth step above the first callout lose a character and gain focus. A redo would reshow the last character.
