Is there a way to change the default tab alignment in Sliding panes. For intance, I have a sliding pane which has SlideDirection="Bottom". In other words, the pane is at the top of the page. The pane title (when pinned/expanded) and the pane tab (when un-pinned), are both justified to the left. I would like to right-justify these, so the pane title appears next to the pin/unpin icon and the pane tab (when unpinned) is all the way to the right.
