SUPER YAY!
It’s an age old bug bear of mine. I have a tabbed browser, but it opens windows for pages from other apps in new windows. Blows.
Never occurred to me that if I told Safari to just open the new pages in the same window it would be bright enough to open them in new tabs. I assumed it would overwrite the current document like IE does. Safari is bright though. SUPER YAY!
That makes me so happy, no more browser window proliferation. Exposé or no, I really dislike having more than one browser window. Works well with my Vim hack (below) as well.
Thanks to inessential.com for the tip off.
