Interesting, thanks.
One thing to consider is that the Buffers tab actually shows the current state of the content, whether the content is visible elsewhere in the UI or not. This is often (but not always, during transitional states) the same thing as showing you the current preset.
Can you elaborate a bit on why you think this would helpful? Is this, for example, because in some cases the text in a Data preset isn't depicted in some layer states?
