Premium Columns and Plan Requirements: Formula, Time, Auto-Number, Connect, Rollup and Mirror

Beyond the basic column types (Text, Status, Person, Date, etc.), Projects ships six advanced types, badged Premium in the column picker.

Requirements

• These columns are available within the plans that include Projects (Crece and up); check your current plan under Settings > Plan & Billing.

The six premium columns

1. Formula: computes a value from other columns on the same item, including text or status columns (e.g. {Price} * {Quantity} or IF({Status}="Done","✅","⏳")). Read-only — it recalculates on its own.
2. Time: a real start/stop timer per task, plus an optional manual base ("1h 30m"). The column footer sums the total.
3. Auto-number: a read-only sequential number based on task creation order (add a prefix like "TASK-" and zero-padding).
4. Connect boards: links an item to one or many items on another board (or the same one), within the same workspace.
5. Rollup: on top of a Connect column, pulls and summarizes (sum, average, count, min, max, concat, etc.) a column's value across the linked items.
6. Mirror: also on top of a Connect column, shows live (unsummarized) the value of a column from the linked items.

How to add one

1. On the board, click Add column.
2. Search for the type (premium ones carry the "Premium" badge).
3. Configure its settings per type (for Rollup, pick the Connect column first, then the aggregation function).

Example

You create a Connect boards column on "Client projects" pointing at the "Clients" board. Then you add a Mirror column showing the linked client's email, and a Rollup column summing the budget of every project connected to that client.

Tips

• Set up the Connect boards column first — Rollup and Mirror both depend on it to know which items to look at.
• A Formula column can read a Rollup's result to run a further calculation.

Troubleshooting

• I don't see these types in the picker: confirm your plan includes Projects and that you have permission to edit that board's columns.
• Rollup or Mirror shows empty: check that the Connect column has at least one linked item, and that the chosen target column actually exists on the target board.
