automatically when they change value and just discovered that I should
also call it on-super-window-show when I change tab, unless I change
my input widgets from calling this on their own tab
well enough; at least when some
more bugs are squished. It seems that alignment goes back to
left-aligned under certain edits. For example if I have a text-field
with an initial value of 0 and replace that 0 by anything else it gets
left-aligned.

Is there a better way? If not then perhaps some form of string-strip

I like how you show one way of converting a match to an object, and then
