Every list table in Ceum — clients, projects, tasks, invoices, transactions, subscriptions, and time entries — lets you choose which columns to show. Open the Settings button (the gear in the page header) to pick what's displayed. Your choices are saved per table and per user, so each table remembers your layout and it follows you across devices and reloads.
On the Tasks page these column controls live inside the same Settings dialog as the "show finished tasks/projects" options, so there's a single Settings button.
Choosing columns
The Settings dialog lists every column you can turn on or off, with a checkbox each. Unchecking a column hides it from the table; re-checking brings it back. Nothing changes until you press Apply — Cancel discards your edits and leaves the table as it was.
Some columns are always present and aren't listed in the dialog: row selection checkboxes, the row actions menu, the expand caret, and the entity's name (which is the link to open the record). These stay put so a table is never left without a way to select, act on, or open its rows.
Only meaningful, user-facing columns are offered. Internal identifiers are never shown as options.
Defaults
Each table starts with a sensible default set — the same columns it has always shown — so you only need to open the dialog if you want to change something. The one exception is the Tasks table, where the Deadline column is hidden by default; turn it on from the Columns dialog if you want it.
Because defaults live in the app (not frozen into your saved choices), any column added to Ceum in the future shows up automatically unless you've explicitly turned that column off.
Status columns
For entities that have a configurable status — clients, projects, tasks, and invoices — the status is just another column you can turn on or off, shown as a labeled badge in its configured color (see Custom statuses). Hiding the status column doesn't affect the status filter, which stays available so a filter you've applied never becomes stuck.
Transactions and time entries have no configurable entity status. Subscriptions show an active/inactive badge as its own toggleable column.
On mobile
Per-column customization is web-only — mobile list layouts are fixed. The mobile app instead offers a compact mode that condenses each list to single-line rows; toggle it from the mobile settings. It's an on-device preference and isn't tied to the web column choices.
