Quirky, but cool, collaborative text editor SubEthaEdit is out today with version 2.6, which adds everybody's favorite (relatively) new UI item: tabs. Of course the main reason to use SubEthaEdit remains its collaborative features, nonetheless the addition of tabs is definitely a strong secondary reason to consider it over text editors stuck with the older drawer paradigm for multiple documents. Personally, I'd really like to see TextMate follow this trend by divorcing tabs from projects. On a side note, I have to agree with Gruber that ???T should now universally belong to the "New Tab" Command (and not the fonts panel as is the OS X standard respected by SubEthaEdit and other applications).
SubEthaEdit is $35 and a demo is available.
