Certain times I use my G1 a lot in a short period of time but keep turning the screen on and off. Examples: using a shopping list application at the store, using Pandora at work (I turn on the screen to see the song names.)
I use the screen lock feature that requires a pattern to unlock the screen. In those cases I'm unlocking the screen every couple of minutes, over and over. It's a chore.
I think it'd be nice if there were a setting to give yourself a grace period. Once unlocked, the phone remains unlocked until the specified time has passed. Say, one hour. During that hour you would only need to enter the unlock code the first time. After that you simply press the menu key to open the phone.
The interval of the grace period could be configurable: 10, 30, 60 minutes, or 0 to act like it does now.
I created a suggestion in the Google Product Ideas. I don't know if it's the best place to suggest the idea to Google, but it's what I found.
If you like the idea, give it your vote. You simply log in with your Google account. There's no way to link directly to my suggestion, so I'll link to a search instead. It's the only result right now.
