I don't know if anyone would think this would be useful, but here goes:

A global timer delay.

When programming a macro, it seems that most, if not all, commands need some amount of delay between each command. And in cases where you are setting up a macro that has many steps (like favorites or mega changer DVD slot selection), you would use the same delay over and over again. It may be useful to be able to specify a global delay at the start (or actually anywhere) in the macro that would automatically perform the delay after each and every command (from where that global delay was specified). It could be additive to a delay manually specified in the macro as well.

This kind of thing could apply to all of the MX editors.

Just a suggestion. Thanks for reading this.
