You are not wrong, but criticism levied at Adobe products (and I haven't used them in 5 years) is often actually unbeknownst to the person making the criticism, about the lack of state control and visibility in the UI. You can mess up your UI state to such a level that the application is unusable. The undo/redo mechanism affects the data (movie, the image, the sound) but it has no effect on the state of the UI. Adobe did implement "reset workspace" or whatever it was called, this was a gift from the gods, but it did not go far enough.

Tooling this complex needs to provide controlled methods for controlling state, both in the tooling and that tooling's impact on the data it is operating on.
