The English language pack is not loading. Currently, when I want to check spelling, only the Danish language pack loads. I don't understand why, because I apparently had the English language pack already installed in the dictionary.

great idea.

I couldn't change the default language to display menus and web pages from British English to US English, then discovered that the Debian distributed v68.11 does not include eng-us in its metapackage of 'all languages support'! Installing eng-us from here fixed the setting in Preferences > Language. Trivial but triumphant!
