[ubuntu] dictionary embedded in task bar (like in 10)

view story

http://ubuntuforums.org – Hi there. I upgraded from 10.something to 12.04, and now the taskbar behaves really differently. I used to have a dictionary app embedded in the task bar at the top of the screen. It was great for writing, because I didn't have to launch a new program, it was just this convenient little bubble that was always at the top of the screen where I could just look up definitions, use the thesaurus, etc., all offline . I haven't found any way to do that with 12.04. I know that there are dictionary programs out there, but what I'm looking for is more of a "widget" that's permanently on (Hardware)
