Smart undo/redo

[dg-pb]

Problem description

Say I write:

big table

Then I undo until only 1 word left

big

Then I type another word and I have

big tree

But I want to get back to

big table

but I cant

Preferred solution

Cool feature would be to be able to enable "include 'undo actions' to undo".

So in a sense it is another undo level.
1st tracker would be the usual actions.
2nd tracker would be usual actions + undo/redo actions.
Then user could enable 2nd level undo which goes back along second tracker.

Alternatives

I don't know any.
