I think it would be great if you could change the title of any window using ShellEnhancer. I just discovered I had three Putty-windows open to the same host, so all I saw in the taskbar was three times "myusername@host". Not very informative, considering it could say "IRC", "emacs" and "shell". I know there are a dozen of programs that can do this (such as this
which is shareware and rather expensive compared to what you get) but as SE is a must anyway, I thought it could be included in it, too.
