All-in-One Calendar stores events as a custom post type with iCalendar-friendly meta: start and end timestamps, venue and address fields, category, and a recurrence rule. The front end ships month, week, agenda, and poster views; the admin side is the standard WordPress posts table for the events CPT with no venue or category columns visible.

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

The grid is the planning companion to the public calendar. The front end keeps rendering month, week, and agenda views for visitors; the admin gains a screen that answers the planning questions those views were not designed to surface.

All-in-One Calendar's strength is its iCalendar alignment: clean meta, structured data, and a public front end that renders every view a visitor expects. That same alignment is why a real grid matters in the admin. The meta is already structured (start, end, venue, address, category, recurrence) but the WordPress posts list is the wrong shape to read it across venues and weeks.

Treating events as rows in a sortable, filterable table 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 category review), and the team spends less time clicking through the per-event editor to discover what was already structured in the meta.
