Dolphin

Dolphin is a new File Manager for KDE, which I encountered when I upgraded to Kubuntu Gutsy. It's supposed to be lightweight with the sole purpose of being a file manager, unlike Konqueror, which is a complete web browser.

There has been some talk about adding tabs to Dolphin. I missed the tab feature initially, being used to konqueror and firefox. But I realized that I don't really need tabs, except when copying files from one location to another. And for that, there is something called "Split View" in Dolphin. I find this better than tabs actually...
