I once was a KDE desktop user... Lasted quite a while. But over time I went to Xfce4.... Been using it now a good while, but one applet from KDE is sorely missed.
There was some kind of panel applet, that was URL aware. Any time you highlighted text that looked like some kind of URL, a dialog window would open and offer to open it with whatever application normally opened such a URL. You might highlight a URL in a man page, text file, or even in the scrollback buffer and the dialog would be right there offering to open it. I wondered if there is anything like that for Xfce and if anyone knows what that applet it? I am awaiting an answer from Xfce user list on the same question.
