System fields vs the columns you add
Every board row renders the same fixed set of system columns in a fixed order, with your custom columns slotted in after Status. Knowing which is which explains why a cell is editable — or isn't.

What it does, and where the data comes from
The board grid always renders Item (the flexible name column) first, followed by Owner, Assignee, and Status. Any custom columns you've added come next, then the remaining system columns in a fixed order: Start date, End date, Due date, Duration, Source, Updated, and Classification. A colour stripe and a selection checkbox sit before all of it, and a row action menu sits after. Every one of these — system or custom — can be shown or hidden and resized independently from the Columns panel, and your choices are saved per board.
Which fields a sync owns
Assignee is the read-only person your connected source assigned the issue to — hidden by default, and you can't type into it. Source and Updated are also sync-derived and read-only. Owner looks similar but isn't: it defaults to the synced assignee, but you can override it by typing a different name, and a "Reset to Assignee" control appears once you have. Everything else on a manual row — name, status, dates, duration, description, and every custom column — is yours to edit directly. On a synced row, the underlying issue fields stay a read-only mirror of the source; only the fields Deckgauge itself owns (like Owner or Classification) are editable there too.
The roadmap doesn't share this Columns panel
The roadmap view has no column picker of its own — don't go looking for one there. Its Size, Start date, End date, and Duration values, which control how a bar is drawn on the timeline, are edited per row from the item detail panel, the same way as any other field. What the roadmap does have instead is a Settings panel (top-right, for anyone who can edit the board) for the timeline itself: its own Start date, Visible quarters, a Size duration in weeks per size label, and a visibility checkbox per group. See Roadmap view for the full rundown.
Classification: where CapEx/OpEx lives
Classification is a system column with three values: — (unclassified), CapEx, and OpEx. Change it from the row's own dropdown — editing one row updates only that row, but if the edited row is part of a multi-row selection, the change fans out to every selected row at once. Classification feeds the CapEx/OpEx cost layer on the timesheet Report, so setting it correctly is what makes that report trustworthy.
If it looks wrong
| Symptom | Cause | Fix |
|---|---|---|
| Assignee cell won't accept typing | Assignee is a read-only synced field | Edit Owner instead — it's the editable equivalent |
| A custom column shows in the wrong place | Custom columns always render after Status, before Start date | This is fixed — reorder within your custom columns via the column manager instead |
| Looking for a Columns button on the roadmap | The roadmap has no column picker — it has a Settings panel for the timeline instead | Open Settings on the Roadmap view, or edit Size/dates on the row itself |
