Hi all! Say, I just realized I might be able to make my question a little bit clearer. The text has been "merged down" into the layer below it. What's the opposite of "Merge Down"? I think that's my question. I think...
To any and all that respond - thank you.

You will have to go to Edit/Undo or windows/dialogs/undo history, and look for the time in undo when you merged it into the other layer/layers. Then click that history layer and you will be back to that time in the creation of your work.
Sort of like time travel - without the perks.

EDIT /UNDO

if you have not already closed the image

May be better use Layers/New Layer from Visible instead then merge down:
Result will look identical but will remain editable

Ninja posted by Rod but i submit the same because you may found useful the tip about New Layer from Visible

Actually PC named a couple of great points to remember -
1) use new from visible.
2) if you close the image all undo history is lost.

I just got an idea from that

Maybe for an update to GIMP they could give you an option to save the history as part of the XCF... the reason I say option is cause it may greatly increase file size.

GEGL was designed to lose destruction in an image.
Gimp-2.8 may be the answer.I know they were working on non destructive layers.Which means you could blur your image then resize it go back and undo the blur and keep the resize without having to go through steps again.

Photo Shop should drool.

Can't wait

I probably shouldn't have posted that.
