-qa should find out how big the terminal is, instead of assuming 80 columns.

Perhaps we should have an /etc/extensions_suggested (extension-application mappings that are overridden by a user's preferences ... this is hard without bloating user preference files)

Wildcard support (or full regular expression support)

Filter support.

Test heh with versions of perl < 5

BUGS

User-defined shell scripts aren't recognized as valid applications, and must be entered into the .extensions file manually.
