YMail poor design

YMail poor design

Very poor design for the new YMail [mail.yahoo.com]

Open mail.yahoo.com and:
1. go to mail messages list
2. select all messages from the top-left checkbox
3. click on "forward" from the horizontal menu (I was thinking "can you do this"? at first)
boom! a diagnostic messages says "Impossibile eseguire questa operazione su più mail simultaneamente. Seleziona una sola mail e riprova.", which can be translate
"Impossible execute this action on several mail at the same time. Select one only mail and try again"

Suggestion: Why don't you simply disable the "forward" click when more mail are selected?

Very very bad design....

note: screenshot exposed here has Italian language UI. Sorry, couldn't figure out how to switch to English.
