Prepared to have a look?

[Fibre]

Is it possible for me to create 2 new users (me,wife) and drag and drop the installed packages into these new accounts? Or do I have to start from a clean slate? Or is there a better way of achieving my desired outcome?

Easy.

1) Add each user using the adduser command.
2) Log in as either user
3) Run program

No need to move existing packages/binaries and no need to start from a clean slate
