It also preserves ordering when moving things (hence my snowplow approach).
Soon it'll summarize what you did that day so you can feel good about what you get done - that's coming shortly, I'm testing the feature for another few days.
There are a bunch of settings to tweak this - picking what reminder lists to include, setting a time window for when it'll reschedule things, etc.
This should link to it:

I'm curious because I'm also interested in hacking the Reminders app via its API, to add some features in a side app
