I'd like to see a feature in which I can get an inbox notification from myself in a set number of hours/days, attached to a particular question. For example, I might ask someone to improve a post, or might be interested in seeing what new answers have come in (sometimes this will trigger an inbox response, sometimes it won't, depending on whether I've answered/commented/edited and what form the response actions took). Today I promised a bounty on someone's question, but need to wait for a couple of days before it can be offered.
For the time being I paste a question URL into my online calendar, but it would save me some hassle for this to be a bit more integrated. Likewise I sometimes ask an OP to remind me "in a couple of days" but it would be nice to be able to be a bit more proactive.
What you reckon?
