More options required for 'Returning from blank screen'

[bluenova]

More options are needed for when the screen should be locked after blanking.

At the moment the options are:

0 Seconds
30 Seconds
1 minute
2 minutes
3 minutes
5 minutes
10 minutes
30 minutes
1 hour

Smaller numbers should be available such as 5 seconds and 10 seconds so that if a screen goes blank it can be woken straight away without entering a password. 30 seconds is too long and poses a security risk.

Allowing the user to enter their own hours, minutes and seconds would be ideal but if it must be a drop down list then 5 and 10 seconds should be added.
