it's X, Y, then Z
Having them labeled X, Y and Z doesn't say much. It should rather say East, North and Up
what do you mean by "event searching"?
Probably something like how the start menu in Windows 7 works.
Instead of scrolling all the way down or look for a specific event, you just have to type "o" to find all events starting with "o" like OnVariableTrue.
This would make eventing much more efficient. Especially with a huge list.
