One thing I really, really want in Swing is this:

specifically the context sensitive placement of the toolbar and menu
access in relation to the tabs i.e. same level (vital to preserve
space) and far right.

As far as I can tell I could do it if I subclassed JTabbedPane,
override one of the paint methods, draw the images, add mouse events
to rollover images and interact on click.  But, no doubt I would
eventually run into problems (especially with changing lafs).

I havent tried it but I assume with JDK 1.6 I can create a toolbar on
a JPanel and then use the panel for the tab portion of the tab.  A
long toolbar might look silly but perhaps the following looks decent:

What do you think?
