QtCreator detached help window doesn't show search/index sidebar
I've recently switched to QtCreator 3.2.1 and I'm a big fan of dualhead development. So I'm used to having a detached help window open on my right screen permanently, using it either via context-sensitive F1 or by directly searching in the index of the documentation.
The detached help window used to have a sidebar itself which showed a search edit and listbox with results. However, it seems this isn't present any more (at least by default) in QtCreator 3.2. Did anyone else notice this, and is it known how to get the sidebar back in the detached help mode?
I'd just like to make sure I'm not missing something, before filing a regression bug in the tracker.
