I haven't yet written a review about Omnibar, sorry about that. This is an excellent add-on that really brings a new feel to firefox. It works perfectly and, for those who care about it like me, it is a space saver while retaining full firefox functionality.
In answer to willmans: I suggest you try the Omnibar Plus add-on with its organize feature, it does exactly what you suggested.
