Red Alert II for me would be great. A plea to the various lab engineering teams: please create a json format or whatever that lets me configure this with voices locally. I am a happy user as of late of the Codex app by Open AI. It would be great if I could just give it some JSON somehow and it just works. I suppose skills can do this and I will try that later on. But I think this stuff matters, and it would be nice to have it built in and encouraged.
