This could have been a tutorial for Ubuntu, Arch, Antergos, Solus … I3 configuration is identical on all these systems.
We made this tutorial to answer the following question.
Can we tell i3 to open vmware player to open on workspace 7 all the time?
You can do this anywhere in the config file but to keep things organized a line will be added in the ASSIGN section.
assign [class="Vmplayer|VirtualBox"] → 7
