I haven't been on for a few days, so sorry for the delay.
Something like the rain editor sound interesting. For the National Weather Service, twice a day I report new snow depth and snow on the ground, and on Wednesdays I report the Snow Water Equivalent (I melt a core of snow.) For CoCoRaHS, I report new snow and total on the ground each morning, and SWE on Mondays.
I don't see a need for all of that, but the option to report daily new snow and have it accumulate for monthly totals would be nice. I don't see where total snow on the ground would be beneficial, as that constantly changes as we get new snow, it settles, or melts.
