I submitted a paper to an Elsevier journal which is now in 'Submitted to Journal status'. Now I want to remove it to improve the write up, though the content is good. I don't want it to be rejected after waiting for 7 months which would be a lot of time wasted. I would rather remove it now and improve it myself or with the help of editing services. Should I email editor to remove it? I am worried because the reasons for withdrawals mentioned on their website are serious and I don't want to give that impression when my reasons is just to improve the manuscript.
When you feel your paper does not have high chances to get accepted, do you keep on working on it during the review and re-submit to a different journal when it gets rejected eventually? Or remove it immediately, work on it and submit again.
