I’ve updated the Yojimbo widescreen hack for version 1.5 (which supports adding images and icons by the way!).
Yojimbo.zip (Yojimbo Widescreen hack)
This hack is for Yojimbo v1.5, and has only been tested on Leopard. It should work on Tiger too, but I can’t guarantee it!
Backup Yojimbo first. Nothing bad should happen, but belts-and-braces, you know? Also, if you get sick of this view and want the old one back, just replace it with the backup.
To install, ctrl-click on Yojimbo in the Finder, choose ‘Show Package Contents’ from the context menu. Navigate to /Contents/Resources/English.lproj/ and replace the OGMainWindow.nib file with the one in the download.
