There are a few ways to customize/refine your Calendar view to help focus your attention:
Filters - configure ad hoc or Saved Filters for Content Items based on Creative Brief Fields (e.g. Campaign, Content Type) or other relevant criteria (e.g. Users) to refine what Content Items are displayed.
Colours - change the colour of all Content Items based on single primary Creative Brief field colours
Week/Month/Quarter - quickly change your date range to review near or longer term Content Items
