On top of that I also use Ability Icons for Marco Icons (to be displayed in the USER MACROS window, not on the hotbar/crossbar) to differentiate macros for different jobs/classes and I can also quickly tell what each macro does by assigning the macro icon to be the same as the first ability to be executed by the macro.

All of that is gone now. Your macros would have to use those new generic icons that tell you absolutely nothing about the 100 macro that you can create. You will have to hover over each macro to see what's what. At least make it consistent by making the Macro Icon in this macro editing window to be the same as the one assigned by /micon.

I too am afraid to edit the macros I created before 2.2. It's outrageous to remove features after a major update for no reason.
