I would like for more details out of the "Usage" panel. Ideally, I would like to be able to see usage for things such as:
* Last hour
* Last 24 hours
* Today (since midnight)
* Past 7 days
* This month (as of 1st of month)
* Last 30 days

It would also be very useful to be able to reset the usage counter whenever I want. Even if you gave us none of these other items above, being able to reset it whenever I would would really help out and make tracking deeper stats like the above easier for me. I use heavy tethering to a variety of services and the usage helps me to more easily keep an eye on my data usage per service from one simple place.
