App settings
The App settings panel controls the global properties of your application. Open it from Config → App settings (the first panel in the sidebar).
Fields
| Field | Description |
|---|---|
| Application name | Short identifier used internally (read-only after creation) |
| Application label | Human-readable display name shown in the navigation header |
| Definition | Brief description of the application's purpose |
| Language | Default UI language (en or it) |
| Status | on = fully active; off = read-only for non-admins; freeze = no writes at all |
| DB engine | sqlite, mysql, or pgsql (set at creation, not changeable here) |
| Max image size | If set, uploaded images are automatically downscaled to fit within this pixel bound |
Status values
on— normal operation; all users with the right privilege can read and write.off— only admins and super-admins can write; other users see data in read-only mode.freeze— the entire application is read-only for everyone, including admins.
Use freeze before performing a backup or migration.
Appearance
The Appearance section lets an administrator pick the application's primary colour. The change takes effect immediately (live preview) and is applied to every user the next time they load the app.
Eight palette options are available — all tested in both light and dark mode:
| Swatch | Name |
|---|---|
| 🟣 | Indigo (default) |
| 🔵 | Blue |
| 🟣 | Violet |
| 🟢 | Emerald |
| 🩵 | Teal |
| 🟡 | Amber |
| 🌹 | Rose |
| ⬜ | Slate |
The selection is stored in bdus_cfg_app.color (added by migration M025) and is read at login time from GET /api/info/app.
