I am using version 1.6.2 which seems to be the newest available in Play. The option I have selected is 'Do not disable on phone ring' which is what I need to ensure adequate security. Unfortunately it is being quite literal in its interpretation of that. If I have already unlocked the screen I do not need it relocked on an incoming call, but if the screen is locked I do not want it unlocked (as this would mitigate any security provided).
Is there a feature request tracker? I think what I require may be new functionality.

I have the Unlock app to 'Do not disable on incoming'. However, it does this even if the phone is already unlocked.
For my use case I do not want the screen to lock on incoming call if, and only if, it is already unlocked. Is this possible?
I have tried searching but to no avail.
Steps to reproduce:
Set app to not unlock on incoming call.
Unlock screen.
Get incoming call while screen is unlocked.

Expected: screen remains unlocked to accept call.
Observed: screen is locked, requiring another unlock to accept call.
