It seems they'll be here for a long time, however this discussion looks very similar to ideas of an itemviews-ng project (https://blog.qt.digia.com/blog/2008/10/24/itemviews-the-next-generation/). I didn't look quite close at this project and i wonder - is it used in qt5 somehow in QML world, or does QML still uses QAbstractItemModel and friends?

I just hate that column view and this "up-up-up-the-file-hierarchy-change-to-next-sibling-and-down-down-down-again"-navigation style which is enforced upon me my the Finder (and the lack of a proper - sic! - tree view).

I tell you, that drives you *crazy* without a tree view - there! again! - on the left side or so... (Not to mention that the Finder *still* lacks a "File Cut" (CMD + X) operation, even though the menu entry is there (greyed out), probably since OS X 10.0)

Andre, that's interesting! Could you link me to the sources of that
new model implementation?
Is there any intention of making that model class publicly available?
