Comment 1 for bug 847457

Sincerely I'd like it too. But, to say the truth, I never asked because I fear that snapping targets would increase exponentially on my drawings (I use so many guides...) so whenever I need such intersections I just draw a segment on the guide (very easy with snapping nodes) and, after snapping to the newly created intersection, delete it (sometimes I recycle it a few times before deleting).
I find this solution quick enough for my needings.
Of course if this is going to be implemented without aggravating too much my poor Pentium IV, consider a +1 from me :)
