If I pop out a region in a borderlayout by clicking on the empty area, it doesn't automatically retract, nor does clicking outside the area make it retract. Is this behavior expected in 1.0?

Also, I don't like the way the inactive tabs look on the vista theme, there is nothing distinguishing the end of the tab. It needs at least a border, or more likely an image.

/*  old
.x-tabs-bottom .x-tabs-strip .x-tabs-right {
	 background:transparent;
}
.x-tabs-bottom .x-tabs-strip .x-tabs-left {
	 background:transparent;
}
*/
/* new */
.x-tabs-bottom .x-tabs-strip .x-tabs-right {
    background:transparent url(../images/vista/tabs/tab-btm-inactive-right-bg.gif) no-repeat bottom right;
}
.x-tabs-bottom .x-tabs-strip .x-tabs-left {
    background:transparent url(../images/vista/tabs/tab-btm-inactive-left-bg.gif) no-repeat bottom left;
}

Using the inactive images seems to make it look a lot better.
