When the original Buttonhole was killed, alot of
people were sent steaming into unknown depths
of anger. Seeing an oppurtunity, I pounced on it.
Hence, Buttonhole Advanced.

Completely rewritten and with more features to
use, it's the ultimate Buttonhole.

        Classic Mode:  |cffff8888(SemiWorking)|r

In classic mode, Buttonhole Advanced behaves
just like it's predicessor. It hides all the
buttons in one, allowing you to scroll through
them with the scrollwheel.

        Menu Mode:     |cffff0000(Not Working)|r

In menu mode, all of the buttons hidden in
the buttonhole are accessable through a menu,
shown when you left click the button.

        Expander Mode:

In expander mode, all of the buttons only
become visible when you toggle the button-
hole.

        Off Mode:

This is obvious. This mode disables button-
holing.]];
