I've found this nifty plugin that claims to do exactly what I want, but unfortunately it's out of sync with ExtJS 4.2.1's FocusManager.

The plugin functions basically like a TabPanel with tabPosition: 'left' declared and the tabs are displayed in such a way that the text is still horizontal.

Honestly, I'd simply like to use TabPanel with tabPosition: 'left', if only the text could be displayed horizontally...

Has anybody else on here run into the same problem before?

Thanks for reading!
