the user is able to select a large block of untranslated text to be sent to readlang learning mode.

Essentially, if there's a section that's difficult and the user wants to study it in context, they'll be able to select whatever quantity of text they like and sent it off to be studied without translating.

I like this idea for moving readlang beyond translation. Breaking down texts and studying difficult passages with a little more context than is already provided for in the system
