I've heard about SerenityOS from the videos on YouTube and I'm impressed over its 90's GUI and some of the new OSes that have their own desktop environments and have the case for integration rather than a separate kernel + desktop environment, etc.

Are there any plans for 64 bit support? and in general about SerenityOS's internal GUI system, how does it compare to RedoxOS or more similarly Haiku which language and GUI development wise, it is almost exactly the same.
