I tend to do like Bob and name macros as soon as I create them.  And like Hosko, I bounce between the macro registers and the macro timline pages as I build, later tightening-up timing in the effect menu.  As far as organization goes, I tend to put macros that I insert into timelines at a higher resister location -- that way as I build, I know there's a group of registers (say 200-250) that I'm working with and don't have to scroll too far to find what I need.

I use the forward and back buttons on the menu to jump from the macro page to the macro timeline page. I don't use that many timeline macros though mostly because we don't use that many timelines here. Most things like clip transitions are built as macros instead.

While a cheat sheet is helpful, I try to name my macros as soon as I create them and the name is fresh in my mind.  Then when going to build a timeline, I can just go to one of the flexi-pads and cycle through the pages to find the macro that I need.
