Photoshop Layer History

What about this idea, a Photoshop plugin entitled "Layer History". What it does is provide History for each unique Layer. (see link to a mockup picture of it:

- it captures pretty much anything about how a layer was created including brush strokes - the user can move back in time by jumping to one of the previous states and modifying its content (while still maintaining later states) and thus creating a potential uniquely different compounded result. For example,i am able to say, select a brush stroke state and then select a different Brush type, Mode type, opacity which would automatically update the stroke inside the document to the new modifications, but also keeping the other states (possibly other brush strokes, etc) that follow it. - it stores information about when the entry was made and allows for internal commenting, creating folder sets (you can select a group of states and organize them under folders for quicker access), color states based on type and by sets, reshuffle states, and modify them. Because the Layer history information can get huge (e.g. Brush strokes) there is a compression technique while it stores Layer History information inside the PSD file (while saving). - discard management options that can allow the user to select the # of states (or types of states) that can be in the window before they are discarded (or converted into a Snapshot). - Because subsequent entries may be the same e.g. multiple Brush strokes, it is able to know when more than 1 entry is of the same type and thus this icon appears to the left of the first of its type. When the user clicks the arrow it collapses (hides) all states of that type (leaves the 1st entry though) thus clearing out space for the user inside this window. If the user clicks the collapse arrow again (now shown as an expand arrow) it re-expands the content revealing all the items of that type.
