Learnability is one aspect of usability. If you want to use Jakob Nielsen's
definition:
http://www.useit.com/alertbox/20030825.html
The others, such as efficiency, memorability or satisfaction, I cannot comment
on, I couldn't get past the first one. Error correction I have to say didn't
work very well for me either.
The scope of features doesn't really seem to fit into the usability equation.

I misstated that. Let me try again. I've never seen a piece of free,
enthusiast (Linux, Open Source, Lego, HAM radio operator) written software that
has had usability analysis done on it.
Even if the code was open for people to add, the FOSS process is not conducive
to allowing for major user interface architectural changes. Most FOSS projects
are written either by people who have zero understanding of UI, and most source
changes tend to me ports, hacks or bugfixes, not fundamental design changes.
LDD has the greatest chance (out of all the tools) of having that put as a
priority (as it's a commercial, sales oriented tool), though Ted's observations
seem to say differently.
The fact you have some ideas that won't get implemented is a shame.
