Report a bug
Something's not working?
Tell us what happened and we'll look into it. The more precisely you can describe the steps, the faster it gets fixed.
Two things worth knowing
Losing data is never expected. If a task or a whole room has disappeared, say so in the first line — those jump the queue.
Wanting something new isn't a bug. If the app works but you wish it did more, put it on the feature requests page instead — it gets voted on there.
