flat view option for tree view

[Matthys]

The new tree view that got added for qadd (and I assume other dialogs like qcommit) is very nice, and I can see how some people wanted it, but in most cases I feel the flat view would still be preferable. Once it has decided to open up as a tree view, you can't get it back into a flat view (I think). Is it possible to at least add an option to the dialogs so that you can choose whether you want a flat view or a tree view? Or otherwise a configuration option, so that each user can decide for themselves which one they prefer?

Thanks
