looks good, a thing i would like to be tested is when the saved position is invalid, like either negative or an enormous value.

this shouldn't break it (is even quite probable a value not being valid anymore because there are less files than the previous session)

The change is fairly trivial, however, due to the fact that the view is not populated and layouted immediately simply scrolling to the desired position on creating the view does not work. Instead a signal is emitted on finishing the item layout, when the view has a valid size and the scrollbar has a valid range. The signal is connected to a slot which scrolls the view to the desired position and then disconnects the signal. For the user, a public function in AbstractItemView is introduced, which performs the connection.
