When posting my answer I check that it doesn't repeat others as required by our FAQ.
In current UI, this becomes difficult when question already has many answers.
I would want that questions with 10 or more answers (including deleted ones) have additional UI allowing me to review each of previous answers individually prior to posting my own.
Side note, personally I would prefer above to be there even earlier, at 5-7 answers; it is proposed at 10 because at this point it becomes way too cumbersome to check prior answers in regular UI.
Such a UI could be similar to one currently used in review queues (which is not surprising as what I want is basically kind of review). Features I would want to have there are:
- allowing me to traverse between answers (next/previous)
- showing me preview of my answer among others, as if it was already posted,
preferably with an option to submit an answer, enabled after I took a look at all other answers
- allowing me to return back to editing my answer (cancel review)
