Exactly. It would be useful if fields could be entered or changed
during play list play as well.

Mmm. An "angel coder" is what I need. I would prefer mouse control
for perusing the wav file. Right click toggles play/stop and left
click positions the play head. Scroll wheel to zoom in/out.

The whole file should be shown in one (child?) window and not be
expandable. A left click anywhere within it should immediately
move the play head to that place and continue playing, while also
showing the part in the 'work' window which would be zoomable and
is where regions would be set. Two buttons would be available to
set the region start and end point and a third to open a widget
to enter data in the information fields.

It would be nice if any previously set region was indicated by
slightly different colouration, or by marks above the wav displays.

Well I can manage without much user friendliness, but developers,
I've found, usually want to achieve a high degree of that quality.

I worked with an extremely competent programmer some years ago, who
took years to learn C and C++, but I was amazed how quickly she was
able to make changes/improvements I suggested. I convinced her to
work on the open source project (SDRMAX3/4), but it didn't end well
and we seem to have fallen out. :(

This is what she (Cathy) did: http://www.youtube.com/watch?v=nae_M_q-i10

Hundreds of WAVs mostly of 120min duration, but only one to be
looked at at a time. Possibly thousands of regions - eventually.

Free, preferably, but I would certainly make a good size donation
if my angel coder made it possible to do so. I certainly can't
afford to pay the going hourly rate. Cheapskate I.

Thanks again.
