If I understood correct, all the "something percence" checkboxes means to user as "show the title of this"?
Show why it is not saying so?
In other words:
"Panel precense" = "Show title"
"Field precense" = "Show title"
So by using this language should (at checkbox fieldtype)
"Label visible" be someting like "Show option titles"
and
"Number visible" be someting like "Show option numbers"
I beleave you can find more same kind of sentenses from the Developer 2006!
I belave can fly! I beleave...Sorry...
Best regards,
