Ask goodnotes is a good thing but needs some pretty obvious, low hanging improvements to be really usable.
When you select "translate" from the quick actions in "Ask goodnotes" you need to enter the language every time! This is incredibly annoying. Obviously it needs to remember your selection.
In addition, the language defaults to the language of the text, which is, in gentle terms, less than intelligent. Make it default to English or to the system's language....
