When working with large cue lists it becomes annoying, as it adds a few clicks and a scroll. It's also harder to check if the right cue was deleted or that a new column is in the right place. Usually when adding a column one wants to ad a cue or a scene, and that jumping off-screen becomes confusing.
The jump happens to the active cue. If cue 1 is active and I add a column before 78, the whole list jumps to cue 1.
