In Logic Editor Example, if I use the default connection router, I can bend
the wires in the diagram.
But once I change to Manhattan Connection Router, I can no longer bend the
wires. Could someone please tell me where in the code which determines
whether a wire is bendable based on the connection router?
Thank you.

Manhattan router is very dumb. It will route connections on top of other
nodes in the diagram. We would like to investigate an intelligent
Orthogonal (same as mahattan, but we need to pick a new name) router, but
have not had time to address such issues.

Randy,
What are the chances of getting a better router added to the plan for 2.2?
Connection routers are very reusable and very important in GEF (and like you
said - the Manhattan router is dumb). I've found Manhattan OK for testing
and prototyping - but real world end users need something better to make use
of applications written on top of GEF. Ditto for anchors. I'd contribute
one to the group, but I'm still in the core functionality stage of my
project and haven't got the time yet for usability issues (sound familiar?).
Something like a smarter Manhatten (no routing on top of nodes, etc.) with
moveable line segments (up/down or left/right) would be great.
