I've found that the quickest way to restore a tab I've accidentally closed is to open a new tab and type a couple keywords into the location bar. OW's history keyword search will pull up just about anything as (unlike Safari) you don't have to type the URL exactly and you can type multiple keywords separated by spaces. Like a Google Instant search of your browser history.

Eg. If I hit Cmd-L, then type "omni tab" this page pops up.
