I've got a bit of an idea about automatically creating entries every morning with a weather forecast and moon phase.
I'm not sure about it. It's a bunch of code (hitting the right apis and parsing the data) but it would be useful to wake up to (except that I've tried this sort of thing before and never used it. I've got weather in my phone desktop and Google to ask and most days I don't look it ask)
I could store the weather at entry save time, and display it next to the time, for a little bit of context. (I could do the same thing with location, through the web location API)
I'll look into it.
