I know from speaking to my friends not involved with Bitcoin that two of their major concerns are as follows: 

1. They are afraid if they fat finger the address there is nothing they can do about it and not get their Bitcoin back.

and/or

2. They would like to at least have the option to use some sort of 2 step confirmation system when dealing ith people they do not know. For example, after sending the Bitcoin to a seller they would like to be able to do a final approval of the tm transaction. If the 2 people involved in the transaction approve of it within X hours, the coin returns to the original person. This system would basically act as an escrow. 

This 2 step system could work with both of these.

I apologize if this is the incorrect place to post this. I did not know where else to share these thoughts.

Thanks for your time.
