I played with the one on your main site with the +/- and it is quite
nice! Only looked at it in IE6 but it worked flawlessly, very well
done :) I'll have to look through that when I have some time..which
is probably never...

Many times when you are debugging a script you use alerts to give you
an idea of a variable value etc. Sometimes this can be quite
intrusive when you are going through a page over and over. In
particular, if you have an alert inside a loop - it can get to be
quite a pain.

What you can do is write that information out to the status line

window.status = myVarValue;

With the one caveat being that if you are writing more than one
thing, it gets overwritten with the next status write. However it can
be a very helpful debug tool. I had just worked on a drag and drop
application and it was very helpful to be able to drag items around
and watch the status bar give me updates on the progress.
