First, I want to iterate that this is not a duplicate of this bug: https://bugs.kde.org/show_bug.cgi?id=185367. This one refers to browsing through the history, as I understand it. What I'm referring to is the awesome feature in KDE 3's Gwenview which allowed browsing through the directories via keyboard shortcuts.

Example usage:
My folder hierarchy looks like this:
~/Pictures/Friends/
~/Pictures/Me/
~/Pictures/Wallpapers/
If I'm currently looking at the pictures in Me/, I should be able to press a hotkey to get to Wallpapers/ (Shift+PageDown might be a good default) or Friends/ (Shift+PageUp). Having to browse upwards to the parent folder just to get to the next/previous directory is tedious, inefficient, and unintuitive, especially when combing through a large number of directories.

This can be implemented exactly as it was in KDE 3's Gwenview - *not* by adding buttons to the default toolbar layout for these actions and thus cluttering the UI, but simply making these actions available as keyboard shortcuts. As far as I can tell, the efficiency that this feature brought to the old Gwenview can't be implemented any other way, and it's still keeping me from using Gwenview 4 as my main image viewer. Thanks for reading.
