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

Instead of: let me buy this app for a few bucks and give it a spin, its now: even if I like this app, do I want to pay for it a few bucks a month for forever?
