I am considering extending the functionality of the extension in the future, probably along the lines of automatically running the line break removal when a copy was initiated from a PDF viewer, and collapsing multiple line breaks into a single one.
Your character limit is an interesting suggestion, I will see how much it fits into the scope of functionality of the extension. Otherwise, I suggest using DeepL instead, I think the limit is the same but it will still translate the first 5000 characters and you can just delete the beginning of the pasted text to have the rest translated. (And it is better from a privacy point of view and, in my opinion, translation quality by far.)
