They are good ideas the improvements in cross-reference, inline equations, citations, Latex importing, ... ... But I think would be an excellent idea to solve the routine copy and paste. Copy and paste use involves crashes, errors, not work from external copy, after paste, the cursor is placed on the end of paragraph, or perhaps in a random place, ... etc

Thank's in advance
