I have submitted a manuscript five months ago and received the first decision of the journal which was "Major revision". The first reviewer recommended accept after major revision. His comments were minor except two comments that suggested we address some questions, which I have decided to leave to our future research due to their complexity. The comments of the other reviewer were all minor. I was able to address all the reviewers comments and justified the reason I left the two major comments of the first reviewer to my future research.
However, the issue is that the due date of submitting the revision is still two months from now and I'm asking:
Would it give a bad impression to the editor and referees if I submitted the revision only one week after receiving the decision?
