MacOS – Which text editors support both tabbed windows & rtf documents

I am looking to change my text editor / note taking app for OS X. I require only the following:

• Tabbed windows: I don't want every document open in a new window. For some reason this seems to be an elusive feature, missing from even many high end word processors
• Able to handle rtf documents
• Does not require an account (many note taking apps do)

Pretty short list eh? I'm coming up with almost nothing. 'Bean' (http://www.bean-osx.com/Bean.html) is so far the only one I've found but it's no longer under development and search/replace feature doesn't work properly.

I know this question could be interpreted as open ended or opinion based, but it is not. I am asking to find out which apps conform to the above requirements, not for opinions about which is best.
