WidescreenMailPlugin for Leopard Mail

WidescreenMailPlugin is a plugin for Mail.app (for Mac OS X 10.5 Leopard) which turns the message view from a two-row horizontal view, to a two-column vertical view.

WidescreenMailPlugin v0.0.4 was released today with the following updates:
- Made the Subject Column show the above it and made the message rows alternate colours.
- Also made the vertical line to change the position of the panes wider.
- Created an application to set the mail options to the default.
