(Get the code!)
Needs a little more input on when / how to do this. I can also imagine a valid use case where you want to have the same equation in multiple places and keep the link instead of repeating them.
There is a similar case for images. If I copy an image to a different page, right click it to open with gimp, edit and save, what should be the behavior ? Currently both pages link to the same page and will show the editing.
Maybe, when you click edit we should detect that it is used in multiple pages and popup asking whether you want to edit all occurences or just this one. (This effectively implements a kind of copy-on-write scheme.) Problem there is that you do not know if the external program that is started is an editor or not.
Now the behavior for equations may be different, but since the implementation between equations and images is very similar I would like a general strategy on how to deal with external objects in copy operations.
Input is welcome.
