It seem that the autocomplete plug-in can only have 1 active auto complete file.
That, If I want to work with 2 different languages I would have to re-import the word file for each language.
Is this true?
Or you can copy autocomplete.dll to another file, for instance, autocomplete2.dll. Then you can define words independently both plug-ins. However, in the next major version — v9, we will include all Auto Complete features into the Snippets plug-in and multiple configurations can exist in the same plug-in.
