There is this question asked where the user doesn't have enough reputation to post images. I usually edit the post to add the image so I can then start to answer the question normally.
I have plenty of reputation to make this edit and it doesn't need to be approved. However, in this case, someone made the edit I was going to do, so I was like: sure, I'll just approve and continue. But when I approve the question, it says: One more person needs to approve this question.
If I have enough reputation to make direct edits, why do I not have enough reputation to directly approve someone's edit? That doesn't make sense, and more so hinders my ability to answer questions.
Improve editand Community will auto-approve the edit.
