I think it would be nice to have a diffing tool inside of Inkscape.
The idea is that we find areas that have change between two versions and it would visually hande a box around the idea showing what had changed.  Ideally as a lay that can be turned on and off.
I know my work would be better if there was a way to show what changed between versions without needing to look at the svg code itself.
Do you think this kind of thing could work?
