Again, just install the normal en hunspell dictionary you get online.

And the extra period at the end of unknown words is not a false positive. It is a truly misspelt word that may or may not be an abbreviation.

Your analysis also ignores the improved suggestions for unknown words that proper handling of abbreviations gets you (ie. no more single capital letters are treated a valid root words for suggestion generation).

Leaving Sigil exactly as it is now allows either type of en US dictionary to be used by the user. So choose the one you want and install it once. Sigil will not overwrite it.

If I can improve it in some future version I will but for now the new version is staying. So please just install a newer or older standard hunspell en dictionary.
