That's not a request we've had before. Users seem to be happy with the more minimal look that we currently provide with the placeholder text inside the input boxes instead of on the side. It takes up less space and, in our opinion, looks cleaner.
With that said, its very easy to override our looks and add labels or anything else you may want to alter on the page. For more information, see our
SCLogin Theming guide
for more information.
I hope that helps,
