Some users have asked to give an additional name to a square so we have allowed them to. However the 3 word system is being integrated into systems where data connections can't be guaranteed, as it is algorithmic, it's only 5MB big which can fit on a smartphone and display/receive 3 words, regardless of whether the user is connected. Available for any devs to use as an offline SDK. Error-detection and voice input are also optimised for the 3 word system. I would focus on the 3 word system.
