If anything, I wish they allow macros with only a single action be queued. For example, something like this:

/micon "Blunt Arrow"
/ac "Blunt Arrrow" <t>
/p "Blunt Arrow used!" <se.1>

I just wrote that off my memory so the syntax might be wrong, but you get the idea. So many times the inability to queue macros with only a single action with a notification message and sound effect makes me end up just sticking to the normal version and forgo the macro. I wonder if they can do an "action count" for every macro and disable the ability to queue only if the action count is greater than 1. Well, it makes a good QoL upgrade but I guess I can live without it.
