It is API-creep going into R1, but adding a simple Undo API and then just using that in BTextView would be a good solution.
Even if it is kept private for now there are several places an undo API could be used within the Haiku applications. Even the new ResourceEdit application has an ad hoc undo system created by an GCI student.

Might not be so simple. As you know, StyledEdit is simply using BTextView functionalities, and that class only supports one step undo. Maybe it's possible to create a derived class and implement a new undo "stack" in there.
