Hi:

Could you tell me the meaning of "as/on a side note"?
I wonder if it means "by the way".
What function does it play?

Best wishes

    A side note is a remark or comment that isn't directly related to the main subject of a sentence/conversation/piece of writing, etc., but which may be of some interest anyway.

    It's not as colloquial as "by the way", but often means roughly the same thing.
