[Plugin: Author Avatars List] Display Options order

Hi have just looked uo last log-in and it seem that WP does store this for users. So I what have to do this. I am not going to just drop this code in just in case it needed. So I will need to turn it on if needed (if a last logged on is select in a widget short code. The question is how to do this. I could just set it on every page load that a the setting is set on.

But it might be confusing if you set this and nothing would change as no other users have yet to log-in and until they have is will in the default order.

I need more info for the usecase for this before I code it.
