The "Go To Line" dialog should accept relative offsets.
* Typing in a negative offset (/-\d+/) should transport you to max(0, current_line_number + negative_offset).
* Typing in a positive offset (/\+\d+/) should transport you to min(maximum_line_number, current_line_number + positive_offset).
This feature would be useful in debugging line numbers from stack traces of embedded documents.
Thanks for your consideration.
