That's right!
With an input box (for text/numbers) it will be perfect!
Thank you for noticing the missing documentation! ;D I actually had it implemented already, but forgot to mention it. It's added now and the files have been organized a bit more neatly. Hope you enjoy it!
P.S.: The "allownumbers", "allowtext" and "allowspecial" flags should help you, they are now mentioned as well, forgot those too!
