Another point to this, is that when emesene loads the contact list at first time, the user will be allowed to interact seconds before while the contactlist is being filled.

This obviously depends of the amount of contacts, cores-peed and cores(lol) you have, in mi case i have tested it with around 660 contacts, and the difference is notable.
