I do not consider a 2 or 4 character prefix offset from the word as "lang-goop". And how does it take any focus away from the word itself, anymore than an entire separate column would?

Nor would I be overloading the word column as language determines the meaning and use of the word.

You also did not address my comment that if a user feels that a language code is too technical, they would be unable to set or edit the lang attributes needed to properly support things. So assuming people understand that de is German, es is Spanish, and en is English is not beyond most users of Sigil.

So I'll wait to hear from other interested parties first before making any decisions.

If there really is only a small handful of users for this feature, then perhaps it would be better as a plugin (edit plugin with a gui) than part of Sigil itself.

The nice thing about this approach is it can all just go away/be hidden when only a single language is used.
