Krusader is a midnight-commander-like QT file manager, more fully-featured/Swiss-army-knife than Dolphin, sort of like the KDE3 Konqueror, but with only a single layout profile, I think, unlike Konqueror, which could be toggled from a Krusader-like GUI to something like Dolphin or simpler, besides a PDF reader or a image viewer like Geeqie. How I miss it.
Anyway, if you want to search something with locate and create dozens of symlinks in a single folder for more careful inspection...
