Until yesterday, when looking at a question on SO, the answer area looked like this:
But today I was mildly confused that now there is a button instead which prevents me from directly answering the question:
I have answered a few questions already and cannot remember having to click on that button when answering.
What am I missing? Can I revert to automatically expanding the answer area?
P.S. When I look at questions on meta I do not encounter this problem - here, the "Answer this question" button does not appear.
I am not sure whether this should really be a feature-request. Please leave a comment or edit the question if it is.
