Make it one-click to disable USA English across all documents, existing and yet to be created.
Every new document I create defaults to USA English which is time-consuming to change for everyone who does not use this variation of UK English. Please make it a button on the 'New document' window to select default language, and please make it a tick-box in preferences. It could be worded like this for example 'What is your preferred default language?" and then a drop down. Then every document I open will automatically have the correct dictionary applied without any further time spent. Many thanks.
You could accomplish this objective by doing this:
Close all open documents, open the Character panel (Ctrl-T) and change the Language option. Then every time you create a new document, your preferred language will be set for that document.
Hope this tip helps.
