Right.

You could do it with the group I guess, but logically it's more of a
multi-value setting element I think. Setting is just a subclass of Group
with one thing, so having a subclass that stores one and a subclass that
stores a bounded set makes sense to me.

Later we could use nested groups to add tabs within a setting group
page, and thus doing this for a band's hi/low settings would confuse
that. The thing he wants is really "the 30m limits, which is composed of
a high and low value".

We have the ability to store the __doc__ bits with the
RadioSetting/Group, which is what that was for. I thought the settings
editor would use those for tooltips, but maybe that never got implemented?

Sure, a ReadOnlyStringValue class that looks just like string but causes
the UI to emit a Label instead of an Entry would be easy. I think Tom
was saying he wanted something like that recently.
