I write for different organisations, and they have very different styles. Academic, popular, easy to translate - some can be totally different from others. The Style Guide feature will be a god-send, EXCEPT that I can only set one set of rules.
I'd like to be able to set different rules in different personas, and switch between them.
Ideally I'd like to be able to export a few rules that I want in another persona, and import them into that persona, saving me time from recreating them all.
