First, let me thank you for this great app! I LOVE Night Stand and I use it every day. Here are two feature requests which I am sure many people would be very happy to see implemented:
1.) Total Darkness mode
Many people need total darkness for good sleep and even the dimmed Night Stand can be too bright for them. Also this would greatly help reduce battery usage. I did some tests: a 100% charged 3GS is drained down to ~25% with the dimmed Night Stand (3G, WiFi and Push enabled). With display off it is drained only to 85% !! Imagine not being waked to an important meeting because the battery has run out during the night!
In this mode the display should automatically go on again when the alarm rings!
Also, in this mode a touch of the finger should activate the display for ~15 secs or so to quickly check the time when one wakes up in the middle of the night
2.) Larger "Snooze" click-area
Most alarm clocks have HUGE "Snooze" buttons - for a reason ;-) I think the whole screen area should be triggering the "Snooze / Turn Off" popup when the alarm sounds. When one is half asleep it is really not easy to touch that tiny alarm icon.
