Not entirely related to little tasks from meetings, but when I need to remember something eg. the next morning but I'm already in bed and dont want to get up to write it down etc, I find that a quick way to remind myself is to take something nearby, for example the book on my nightstand or just a crumpled tissue or two, and throw it on the ground where I'll see/stumble over it the next morning and think "why is this here" and then remember.
