If I store all tasks in a database, then I need to be able to quickly refer to it. Actually, i I can cache it, that'd be nice. K
That means I'll have unique task IDs, which allows me to use pretty good task references.
Most of the time I'll be dealing with just the day's tasks
I want something to remind me what I'm currently working on, and the last few things I've been working on. For example, in a conversation, I may occasionally refer to the last things people say. This would be a circular list.
