It's still quite new, but there's stuff I'm planning but haven't gotten to yet. I'm intending for certain allophonic rules in conjunction with ablaut to make some forms superficially appear suppletive in the romanization, when in fact they are totally regular. This is because the only way the romanization makes any sense at all to an English speaker is for the characters to lack direct matching to the native orthography (which I haven't developed yet). e.g. I want one case form (probably dative) of cent [t͡sɛnt] to be gont [gɔnt] in the romanization, but the native script would use the same character for the first letter of each, because t͡s>g/_ɔ is purely an allophonic rule.
