This could be done by adding a new section, a "Master Macro" section if you will. Right click on a macro within a track and select "Add to Master Macro" to add it to this section. Then you could have macros from different tracks all visible at once in that section.
Or....
You could add a "Macro" section to the mixer, the same way there is a "Send" section. You could toggle it on or off, the same way you do with the other mixer sections (Send, Track Delay, Crossfader, etc.). And right click on a track's macro and select "Add to Mixer" to add it to the mixer's macro section (to prevent ALL of the macros to be added and flooding that section).
Hopefully that all makes sense.
Having select macros from different tracks all visible at once would add a lot to performing and mixing, making it easier and more accessible. I hope you at least consider it!
