I wouldn't want an additional menu item to convert unix text files, but rather an option in the 'Files of Type' list of the Open/Save file dialog window.

While we're on the topic of simple applications, please bring back Terminal from Windows 3.x . Trying to use HyperTerminal just isn't the same when playing with RS232 stuff.

Also, a new feature for notepad would I would like to see would be the ability to show line numbers, but not have this as a menu item, but keep it as a keyboard shortcut toggle.
