This is just sad. Eric Meyer is a person I have tons of respect for, I have admired his CSS as well as his writing for years. Though I think I never commented on his blog and he most likely never heard of me I have been sad for his mother's death and happy for his baby's birth. Such one-way, long-distance, yet personal relationships with someone who writes to share his skills and emotions is a core feature of the web.
So I'm very sad that version 1.1 of his S5 slideshow toolset still uses browser sniffing to exclude Opera from some of the widgets he enhances the slideshow with for other browsers.
if (!isOp) createControls();
As for calling OperaShow "highly browser centric", well is it somehow Opera's fault that Mozilla coders not yet have gotten around to implementing the media: projection goodies from the CSS spec? Eric makes it sound like a proprietary thing though it is all about supporting some of the rarely implemented parts of the open CSS specification. Go vote for some Bugzilla bugs if you want cross-browser compatibility…
