dcarpent - thanks very much for pointing out the first one; obscure failure case we'd forgotten to check for. Anyway it's fixed for the official version, in the meantime if you go into Manage Dictionaries and turn off the "fallback" option for Unihan, that should get it working correctly.
goldyn chyld - you're welcome! We've made a few nice improvements to automation recently, and since there'll be at least a week or two lag before Apple approves the thing we want to be as current as we can manage in spite of that
Earl - on your first issue, what do you mean by 'reverts back to iOS Pinyin input'? Is the problem that you'd like our tone input bar to appear here above the keyboard?
