1. A list of the available washers and dryers in the user's laundromat area.  This list of machines represents each machine as an expandable accordion-style box; once expanded, more details about that machine can be seen.
2. How much time is remaining for a machine that the user has put clothes in and started (see screenshot 2).
3. A specific message should no washers/dryers be available at that particular time.  This functionality also allows the user to be notified when a machine becomes available.
4. The ability to leave notes on machines, read notes from previous users on machines, and indicate that you are about to use a machine.

In our heuristic evaluations, multiple evaluators were confused with what the checkboxes associated with each machine actually controlled.  To address this, we changed the text label next to the checkbox from "Notify me when this machine has finished" to "I've loaded this machine".  We feel that this message makes the checkboxes' functionality much more apparent (see screenshot 3 for example of this).

For our conversation functionality, we decided to include a header at the top providing some very basic information to the user.  This information includes that the user is chatting with a previous user of the same machine and the name of the machine the conversation is centered around (see screenshot 5).
