Offline mode?

[jengalas]

Is there any possibility of using Suma in an offline mode? That is, allowing the user to switch locations and enter counts while not necessarily connected to a network, and then submit the totals at the end?

Suma itself is working well for us, but we have poor wifi reception in certain areas of our building that is causing frustration for staff members, as the connection sometimes drops out when they are trying to switch locations. I realize that the browser saves the counts and they are submitted at the end, which is great, but it would also be nice if users didn't need to be online just to switch locations. If they could walk around the building, do their counts, and then just submit everything when they are back at their desk or another location with known good wifi, that would be very helpful.
