I have these lines in my i3 configuration file:

```
# Startup applications.
exec firefox
exec gnome-terminal
exec nautilus

```

These lines start firefox, gnome-terminal and nautilus as expected, but the order in which they start is unpredictable. Is there a way to start these applications in a way that makes the windows appear in the order that I want? (i.e. firefox, then gnome-terminal, then nautilus).
