Feature request: assign an ID to each icon

[FrostShock]

When you chose the icon for your macro, it would be very helpful to have an unique ID for each icon (button) - a name or at least a number.
And then, when you create a new macro, it would be very easy to find your desired icon, by simply typing it's name or ID number. A searchbox for quickly finding your icon would be also very welcomed.

Thank you
