Joachim,
i registered first to Thank You for this brilliant extension.
I had the idea to make special content articles (for tooltips) and inside them to include php scripts with Jumi, and the thing works perfectly. I think that this opens up great possibilities for managing the screen real-estate, and this is something that should be stressed quite enough!
I also have one question, if you please: i would much appreciate if you finish that "internet explorer solution" thing..
