Healing/DPS/Tank layout switch?

Before the update you could switch which layout to use through the infobar, very useful if you played something like druid with all 4 specs active. I can't find the switch after the update though? Was it removed or am I blind?

It can still be changed but so far I've only found it through the options menu
/real, other, general, layout.
I'm sure some clever person will know how to put this on the infobar/make a script or macro to change.
