I find custom-named widgets easier to work with during development. I can tell
what this is; ".main-frame.data-frame.title-hit-list.-10-". If I didn't assign
names it would look something line this:".2837029.283725.283762.2848308".
Once my program works I can drop custom-naming.
I understand that conflicts may arise if one assigns numeric names.
To find out whether the digits in the label names ('-10-' above) might
be implicated, I changed to spelled-out names ('ten'). The change had no
effect. The reference you list blow (x147-more-on-widget-names.htm)
indeed says "don't use names which only contain digits".

Aware, yes. In the habit of, no. Thanks for the reminder.
