Methinks you are making some very broad assumptions based on one thing that you happen to be doing, and it's not what most people intend to do in that same situation.  Text is linked to prints.  You cannot link text to other text.  It does not follow that just because you tell Qimage you want to copy text labels to other prints, that you necessarily want them all to move together.  Things like copyrights or signatures, for example, are often adjusted (position wise) on a print so that they cover the least obtrusive area, or they are laid over a dark or light area based on the color of that copyright signature.  So a common workflow is to copy a logo, signature, time/date, or other label onto a batch of prints and then manually drag/adjust individual ones so that they don't cover important areas of the image or they appear in an area that is more readable, etc.  Now, could it be an option to "Move all similar labels (Y/N)"?  I think so.  Then people could choose.  So it's a feature that can be added.  But as far as irritating, it'd be far more irritating if Qimage arbitrarily moved every label that was copied among prints.  Now that wouldn't meet the Qimage design goal of making it easy to print great photos!
