I entirely support the request. There's no norm, excluding "ё" from usage, although in most cases it's now Ok to replace it with "е". I use both spellcheck and "ё" and it's very annoying to see all these correctly spelled words underlined. The problem is quite basic, I guess, at least I've never experienced such problems with other software. I'll be looking for some feedback (I suppose as well as OP). Thanks.
