But dragging the straight line from it's middle will still leave the
segment with corner points at the ends, albeit with control handles
extended. You will still have to change the point type in the Point
menu if that's what you need to do.

Using the Point Info dialog you can check the "Default" box to extend
a single control handle from a node. I'm not sure exactly how this
default setting is determined, but it seems to put the curvature in
balance with those of adjacent nodes.

Fontographer had an "Auto-Curvature" menu item, which effectively did
this "Default" for both control points for all selected nodes, and the
state persists when moving the nodes, provided the control points
remain untouched. It's a less precise tool, but a big time saver in
many circumstances and one FontForge lacks so far. (Though some of
this functionality, i.e: dynamic curve adjustment, is mimicked when
using FF's Spiro drawing mode, but in a very different way.)
