Review request for Dolphin and KDE Usability.


Summary (updated)
-----------------

Dolphin: expand all one level, expand all, and collapse all in details view mode


Bugs: 196772
    https://bugs.kde.org/show_bug.cgi?id=196772


Repository: dolphin


Description (updated)
-------

Implemented functions:  Expand All One Level, Expand All, and Collapse All.  They are available via the context menu in details view mode as well as custom toolbar buttons as Thomas explained.  See screenshots.

I did not use the Ctrl+Shift+* shortcut because on my laptop, there is no numpad so it's not possible to generate that shortcut.
