When the dimensional  window  is implemented  will it work 2 ways  and if not their should  be  a  extirior  scanner  so you can see outside  without  being  in danger  say you go to some quards go outside  bam dalek and a cliff *dies*

The Tardis flight panel solves the scanner problem, you can see outside with it. If we're considering the Team's coders (I.e John only :P) the flight panel removed the immediate need to have the player see the outside from the doors.

It would still be a nice aesthetic feature though, maybe it could show the time vortex when in flight. (Suggested by ArcPhoenix in his Tardis suggestion thread)

As for dimensional windows seeing the interior from the exterior is confirmed, but will take time as that alone is a big feature. 

 I think that this feature is still needed as on the public sever only Donator+ can use the flight panel and may people have left there Tardis's and fell of cliffs, out of trees and into lava pools with no hope of getting out of it and living or add a scanner that people that default players can use so they don't die so much

This is a question, not a suggestion. Wrong place.

Also, did you REALLY? need to make a whole thread for this
