Leafcat is planning on changing OR in Alphabest to an O with a bottom bar to make it more consistent with AR being a short A with a bottom bar. Plus, the new OR shape can be more intuitive due to [o:] being an allophone of long O, not short O. Oh, and I will also be deleting any comments that say "just remove OR entirely".
