The EMMET plugin made this :

  - write "td*2" then tab => "<td>•</td><td>•</td>"

  - write "td>td" then tab => "<td><td>•</td></td>"

I think some plug-in have a "close all tag" feature ( maybe emmet ) in other case

I don't think it's a good idea, since I don't use "qwerty" keyboard but french "azerty". If this feature is enable by default only "qwerty" user will maybe think it's fine.

Maybe a Plugins is a better idea.
