I’m not sure I’m the only one bumping into this in every UI Mockup / website workflow, but I find the way Inkscape deals with clones and duplication very unuseful.
We’ve talked about this with Andy a bit during LGM. He was trying to explain why this sort of behavior is desirable as opposed to easy (to little effect I’m afraid). Anyone providing a way to point the duplicated links to the duplicated parent (within a group?) gets eternal fame and my worshiping. Filed a rather sucky bug on this.
Update: Not quite there yet, but it’s a step in the right direction. Thank you Bulia, you already have my worship and fame ;).
