How macros and the action bar can coexist.
I have a very simple request.
1. Create simple icons (allow for color customization) and allow players to create custom macros, and drop these icons on to the action bar next to other class abilities.
2. Consider allowing players to edit lines of macro into existing actions and abilities found on the action bar. (See image below)

===============
In XI I found myself rarely using the menu system as macros were much faster and efficient. From a UI perspective, the action bar is much like the macro menu and this is by no means a request to replace / remove the macro menu. This feature further enhances the use of the action bar and would be a great feature to implement I believe.
