All-in-One Event Calendar Pro extends the free plugin with imported feeds, additional category controls, and front-end views for power users. The data model stays the same: events are the ai1ec_event custom post type with iCalendar-aligned meta for start, end, venue, address, category, recurrence, and contact details, plus Pro fields for imported feed sources and extra metadata.

SleekView reads the same CPT and the same meta, including the Pro fields, and turns them into a real grid. Title, venue, category, start date, recurrence, and source feed sit as real columns next to status and author. Saved views split the work by venue, by category, or by source feed, and inline edits write to the same meta keys the public calendar uses.

The grid does not replace any ai1ec Pro view. Month, week, agenda, and posterboard views continue to render on the front end. SleekView reads the rows in the admin and surfaces them as a list organizers, venue coordinators, and marketing teams open every week.

ai1ec Pro inherits the iCalendar alignment of the free plugin and adds power-user features (imported feeds, additional category controls). That alignment is exactly why a real grid matters in the admin. The meta is already structured, but the WordPress posts list is the wrong shape to read it across venues, categories, and source feeds.

Treating events as rows in a sortable, filterable grid turns the calendar from a public-facing display into a planning surface. Saved views become the rituals of the role (Friday venue check, Monday rescheduled list, weekly source-feed audit), and the team spends less time clicking through the per-event editor to discover what was already structured in the meta.
