Stack steps

Normally a programmer puts all their cues for a show into "whole number" cues.  Then, when the time comes to insert a new cue between ones that already exist, it's very easy to insert a Point Cue and use that.  Yes, it limits you to only inserting 9 cues between each one that already exists, but if you need to insert more than that, it's probably will make more sense to re-record the whole stack anyway...  Another common use is when you use follow times to have it go directly into the next cue automatically -- one might have them all be subsequent point cues so they appear as "parts of the same overall cue".
