i3a-scale-cycle

I added a new script to i3a: i3a-scale-cycle. This allows to use a single comand to predefine some scaling factors for Sway and cycle them. I generally don’t have problems with small letters, so I don’t use scaling, but sometimes my eyes are to tired to bear them any longer. Usage example: i3a-scale-cycle -f 1,1.25,1.5 --next
