Not really - keep in mind interacting with Boss as a Service is a normal human conversation. In that way, it's very fluid and natural. You tell them what you want to work on, they help keep you accountable via reaching out, you report back when you finish it. If you needed to re-prioritize anything, it'd be as simple as saying, 'Hey, I'd like to work on A instead of B' or 'I'm going on vacation for a week' or whatever else you might need to say.

This isn't really a web task/todo list service - think of it more like someone helping keep you accountable to tasks where you'd find it helpful for someone to do so, if that makes sense.
