OK, so this is totally new and I have never seen this implemented in any CAD software. Imagine that you're about to start working on something a bit tricky and you don't know exactly how you're gonna do it. There will be trial and error and you'll mess things up more than once. Using undo in this situation is useful but tedious. You might have to undo many steps.
Now imagine this. You set a named undo checkpoint and call it something like "Before Detail X". You go about your work on Detail X and when you've messed things up totally you just skip straight back to that checkpoint in the undo history by selecting it from the undo history palette.
This should be pretty straightforward to implement as there is already an implicit undo history, we just can't view it in a list or mark checkpoints. If I can undo 10 times then I should be able to instruct the software to just go back 10 steps automatically for me.
In my experience Undo can be a bit volatile as the undo cue will be wiped under certain conditions if AC cannot rewind. I agree with your idea. Perhaps a compromise would be the ability to continue working on the current file and having the ability to "Save a copy as...", you could then create "Before Detail X" this would achieve the same result without relying on the undo process.

And this idea could be extended by creating a "Concept Workflow" tree, where we could establish nodes that originate branches of concepts. This could be very useful to get multiple access to every part of the design process simultaneously. Not to mention that clients could be presented with a graphical representation of the hard work his architect gets to achieve his design objectives.

The tree branch concept could be very interesting if implemented correctly, like a genealogic tree of your design. Meanwhile i end up with around 50 different archives for each project exactly for the reasons described by the OP
Thank you very much for creating this poll, and for those of you who voted to express their opinion.
I am happy to say we took notice of this wish and I have added it into our WishList database (please refer to it in the future as Wish #12686). Hopefully, our Product Management team will adopt this one in the future.
Personally, I think this will be a great feature if we can implement it! I would be happy at least with a History palette!
Thank you all once more, and I wish you a great day!
