dimentinal spawn protection

Read below for reason of the two sugestions. My first sugestion is damage protectiogn for the first few seconds after going through a portal. I think this is a good idea becasue it will stop things from killing people before they can fight back. My second sugestion is fixing the portal spawns, it would save so much time if the portals just spawned right and i wouldnt need to move my portals around just so i dont lose my stuff.

I went through a nether portal and for some reason it took so long that a creeper was able to go through the portal and explode before i loaded in. This broke my portal and made it so whenever i went through the over world side it teleported me to a diffrent place then the original portal. I had to use creative mode to find my things.
