        Lovely :-) it reads more nicely now, I pushed it & good work.

        All looks good to me. I love the improved float icon too :-)

        Heh :-)

        Right; I saw you replaced that.

        Oh - well, everything gratefully received :-) whatever interests you
most is best I think. Of course, some of our bigger, nastier problems
are in the are of user-interface;

        Sure; so - you could poke another easy-hack, or carry on cleaning this
up. There are really plenty of interesting tasks - it often helps to
have several on the queue :-)

        Of course, things that improve the UI are much appreciated by end
users, and there are a number of open tasks in this area that are not
easy hacks if you're interested (Christophe had a nice idea of making it
rather easier to add notes by clicking on the ruler IIRC that might be
fun) :-)

        That's best practise yes, but luckily I was watching for this :-)

        Heh :-)

        Ah - so - this bug is to a dead & obsolete Sun/Oracle bug tracker that
rides no more: it'd be good (in fact) to come up with a nice regexp to
find them all across the code & remove them.

        Sure - poke Lior Kaplan he's the man for RTL queries. I strongly
suspect the comment is right though - I don't think those guys want
backwards ticks in boxes ;-)

        Anyhow - thanks for the great work; looking forward to your next steps.

        All the best,

                Michael.
