This is really a tip for beginning game-makers that I thought I would share because it took me so long to figure out myself.

When you are making your game and you are placing events all over your maps, it can really help to color coordinate them or otherwise organize them in an easy to identify way. For example, events that start automatically could be black. It doesn't matter what the auto-event actually looks like (an NPC or an invisible tile etc), just place a "dummy" tab before the tab with the actual programming. The dummy tab never does anything; it is never even called; but the event on the map will still show up black because of that first dummy tab. It is a little extra work, but this makes it so much easier to edit your events.
