In details mode it is really hard hitting the little triangles to expand/collapse folders. You really have to hit the icon, clicking the huge space left or right of it, or slightly above, will not do.
Steps to Reproduce:
1. Go to a folder with subfolders
2. Switch to details view
3. Click slightly outside the expanding/collapse triangle
Expand/Collapse folder, even if you not exactly hit the triangle itself.
Cannot reproduce. Here the complete rectangle to the left of the folder icon is clickable. Tested with Oxygen and Skulpture style.
Ah, wait, with nested folders, the inset rectangles could indeed be enlarged, up to the border of the view.
(Which is a regression compared to "normal" QTreeView, so actually a little bug :)
Hm, no, for a normal QTreeView, you actually have to double-click, if you are too far outside. Sorry for the flood.
Part of the problem is the missing hover-feedback. With QTreeView, Oxygen style highlights the arrows when hovering them.
I guess another part of the problem is that the clickable area is always (KIconLoader::SizeSmall)^2, no matter what icon size the user chooses in Details View.
@Kai: am I assuming correctly that this is the most important aspect of your report?

Use the icon size from KItemListStyleOption for the width and height of the
expansion area instead of KIconLoad::SizeSmall.
