Can't use preview pane

[gpetit]

Hello, maybe i miss something, but I can't use the preview pane : in the options, I don't have the line permitting it to be shown or not. I have the following :
Language
Time zone
Daylight savings
Rows per page
Prefer HTML
Pretty dates

Do I need to configure something to see the option ? I have version 0.1-beta2 installed.

Thanks in advance

OK I get it work, whith the latest SVN. I didn't notice it wasn't implemented in the the latest stable release

But some skins are not compatible with this new feature, like icandy2... which is not showing the pane.
