I am looking for a word/word phrase native English speakers use as an expression for 'a tiny detail' / 'a small thing' (when mentioning something but adding that it is not so important). I came across the word 'a trifle' but am not familiar if and when it is used in this meaning. Do you say - 'such a trifle'?
Example: Such a tiny detail/such a small thing - I wish there was a night lamp in the room.
Thank you in advance!
