I have a project in which I need a way to display essentially a list of tabs, each with their own content pages, down the left side of the page. I'm using TabLayoutPanels elsewhere to good effect, but after looking at how they are constructed it seems like it would be quite a bit of work to undo Google's carefully constructed layout and get it to work in any other orientation than top-aligned.
This doesn't seem like it would be an uncommon layout, so does anyone know of a successful implementation of this kind of container?
