If you've never noticed (I hadn't)...
If you drag a dimension string, the texts will re-center themselves on their segments, assuming the texts have not been moved manually. Those stay where you put them.
You don't actually have to drag the string anywhere, just a Drag and a double-click will do it.
This comes in handy when you've customized a pair of 5'-10 3/4" texts to read EQ/EQ.
It a has a not-a-bug-but-a-feature feel to it. GS, if it's not intentional, don't fix it!
