As a caster it is often that one needs to promptly use the potion during casting. Adding /stopcasting in the macro would make it much more useful.

@Jerry-Ma You're right, that would be a useful option to include. I've submit an update that will provide this option via the addon configuration. I have opted not to make this the default behavior, as not everyone may want that behavior.

After the change is merged, you'll be able to toggle it on in the options, by typing /ap or via the in-game AddOns options.

This is added with #61
I think stopcasting will come in handy.
