While we're doing suggestions I'd second the
nominations for

1. Better spreadsheet (oh wait, that's what
you call the main window, I guess I mean
list) editing (move group up
or down comes to mind)

2. In both spreadsheet and list format, keys
I'd like either programmable or something like
alt-b - adds bend at to node
alt-y - adds +y at to node with default (user
defined) friction)
and I guess If I'm doing that, then might as
well have alt-G and alt-L with user default gaps.

and while we're at it...

3. Would be nice to have the break command
allow you to pick from which end so I can be
lazy and not have to figure out how much
20'-one flange is all the time.

and some sort of a goal seek, essentially
make the distance from A to B X by changing
dimension from C to D.
