Bug 245089

Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

If you have a great number of nested folders, and you want to traverse all of them to do some kind of operation (e.g. deletion) on allof them, it is presently a pain in Dolphin to navigate. The folder panel is an improvement on the situation, but traversing a large directory tree in Dolphin in its current form is a pain.

I propose that the Folder Panel be modified to implement Collapse, Expand, Collapse All, Expand All context menu options and to allow easy traversal using a keyboard's arrow keys, with left being collapse, right being expand, up being to move up in what is being shown and down being to move down in what is being shown. I realize that symbolic/hard links could cause a problem, so I recommend that a depth first search be done on an Expand All operation, with directories being identified by their file system inode numbers, to eliminate the possibility that Dolphin would try to expand an infinite tree.

An additional feature that could also be implemented would to have Dolphin remember for the duration of its execution any expanded directories that had not been explicitly collapsed, such that if you use Expand All on a directory tree, Collapse on it and then Expand on it, the subsequent Collapse and Expand operations would cancel, and it would be as if you had never done them. This is necessary to have separate Collapse and Collapse All operations. Without it, the Collapse and Collapse All operations would be the same thing.

Reproducible: Always
