One thing that I used to miss on my Eee PC was a run dialog box. With most Linux window managers -- like GNOME and KDE, for example -- you can press ALT+F2 and a small dialog box will appear. Then, you type the command to start an application, and click Run. But Asus, the folks behind the Eee PC, forgot to add a run dialog to the window manager.
Thankfully, the Eee PC community came to the rescue. They're a group of very passionate users who have been doing interesting things with the Eee PC and who have been writing some useful utilities (like the one discussed in this article).
And one of those applications is Launcher Tools, which adds that missing run dialog.
