SUGGESTION : text box & multiline textbox attribute - allow customisation of MAXLENGTH

EDIT
It's great news that we can now set the textbox width ( and multiline height )  (v1.6)

For offering personalisation of a product, it would be really useful if we could also set the MAXLENGTH ( maximum / minimum amount of entered characters  )in a   textbox   attribute  

It would need to be configurable at a per product level rather than in 'all settings'
