The correct answer is coming up with new ideas and topics.
While you are revising your writing, it is important to go through a couple of things:
1. checking for redundant language - get rid of unnecessary words and phrases and rewrite the sentences
2. getting rid of euphemisms and cliches - cliches are never wanted in a writing so this is something you should avoid
3. removing overly complicated language - unless it is an academic or technical writing, there is no need to use overly complicated language
Therefore, new ideas and topics are not something you should think about while revising - revision has to do with grammar rather than the content of your writing.
