Preview a email without opening it

[chriske]

Hello,

There must be a plugin for this somewhere but i cant seem to find it. when i got like 20 new emails i dont wanna double click em before i can read them. I would like a nice window where i can pre read the email.

Example:

http://www.roundcube.net/images/screens/mail_listing.jpg

Found this on the website so it should be possible.

Hope some can tell me what i need to do

It's a default function from Roundcube

Personal Settings  ->  'Show preview pane'

I don't have the "Show Preview Pane" option in settings.  How can I tell what version of roundcube my host installed?
