Using window panes (not tabs) to handle multiple projects

#1

Sometimes, when I open a project with command line atom . atom doesn’t open it in a new window but split multiple project with panes.

I don’t mean tabs to handle files inside the single project:

Does exists some way or documentation to handle this?
It would be very useful to me.

Atom doesn’t have any native capabilities for doing this. macOS forces this arrangement when Atom is in full screen mode.

Thank you, now I’ve understood when it happens.
