Hello,
I'd like to let you all know that I have been working on a new tool for measuring objects in Inkscape. Here is a screencast of the tool: http://www.youtube.com/watch?v=CZKnxTO11xE

But if you checkout the development code from Bazaar , then you'll see some new things that were implemented in the tool after recording the screencast (i.e. the tool now displays angle info also).

Happy Hacking,
Felipe Sanches

PS: If you find bugs prease report them and assign the bugs to me at Lauchpad bug tracker.
