At the risk of being flaming for making a stupid/obvious post, I just thought of something which I've successfully implemented and found to be rather useful. It's an easy way of elongating the amount of macro lines available to you if you play on PS2 or Xbox (or don't use windower).
The new command functions like this: /macro set <number of set goes here>
You can use that to give you essentially 10 macro lines if you're alright with hitting it twice. Basically make the macro like this, starting on macro set 1:
/equip ...
/equip ...
/equip ...
/equip ...
/equip ...
/macro set 2
Then in the exact same position on set 2 make this macro
/equip ...
/equip ...
/equip ...
/equip ...
/equip ...
/macro set 1
If you hit it once, wait a moment and hit it again, it's pretty similar to having 10 lines available to you, it just requires 2 quick keystrokes. Much easier than having to manually move left and right over the macro lists.
