A few optimisations to make me stop feeling mildly annoyed with myself. Connections slide now works in a much neater way, the word cloud is vaguely presentable (although possibly rather arbitrarily so) and the features slide take the whole event set rather than just those events that have yet to be displayed so that they show the appropriate number of events attached to the feature (at least I presume that was what the prolem was before, but the numbers seem more appropriate now).
