Yes - that helps.
Things I notice so far:
From the Home screen, I set up a control called "Living Room." I realized that's not what I wanted to do, so I deleted it. The "Living Room" screen remains as an orphan, and even though I can't get to it from the Home Screen, I can still flip to it.
Thermostats are in Celsius only. I have min/max set on my thermostats, and warnings set up via Prowl, so I can't control the thermostats without setting off warnings (because I can't set the thermostat above 69 deg C). When I set the thermostats to 73 deg F in MIOS web interface, HomeWave shows 75 deg C. If I touch HomeWave, I get warnings from Prowl, and...
When warnings (or other ALERTS, vs. "badges" or "banners" on the iPhone) come in, HomeWave shoots back to the Home screen. That's a pain if you're in the middle of something & an email comes in.
If I try to select an area with a "1x2" block with two "1x1" blocks next to it, I can't. I have to first split the 1x2.
If I add a "No control" empty space or label, I can't format it. No size, color, background, etc.
It seems to take about 5 seconds from the time I send a command via the MIOS web interface on my computer until it updates in HomeWave. Not good, not bad.
It'd be nice to be able to change the format (colors, vertical alignment) of the elements on the Home Screen as you can on the other screens.
