is there a possibility to add more than one unlock buttons, but with different icons and different actions after unlocking.

For example I could have mail icon, and if I slide it instead, I will end up with mail open + unlock.
Same would be for IM and missed calls.

At the end I will have 4/5 unlock buttons and depending which one I'm sliding, I will get different behavior.
Also some actions could happen in advance, for example if I receive a mail, and slide the mail icon, I would like to see my mail ASAP. So lock screen could just start mail upon mail receiving and keep it in background, when I unlock the device, I will just get the corresponding app in focus.

Just ignore it, if it is discussed earlier, I didn't read everything from the beginning.
