## Goals and scenarios

### New Custom Data UI
**Goal** — enable the updated workspace (off by default).
- **Enable Custom Data UI v2** → [./how-to/enable-custom-data-ui-v2.md](/en/customdata/how-to/enable-custom-data-ui-v2.md)

### Access control
**Goal** — who can create tables, edit rows, export data.
- **Role settings** → [Roles and access](/en/settings/admin-hub.md#user-and-role-management)

### Table lifecycle
**Goal** — safe delete and restore without losing row data.
- **Trash and restore tables** → [./how-to/use-trash-and-restore-records.md](/en/customdata/how-to/use-trash-and-restore-records.md)
- **Edit table** (danger zone) → [./how-to/edit-model.md](/en/customdata/how-to/edit-model.md)

### Shared view settings
**Goal** — same filters and columns for the team.
- **Saved views (shared)** → [./how-to/use-saved-views.md](/en/customdata/how-to/use-saved-views.md)

### Import and data integrity
**Goal** — control bulk import and clear-then-import mode.
- **Import from file** → [./how-to/import-data-from-file.md](/en/customdata/how-to/import-data-from-file.md)
- **Import from Google Sheets** → [./how-to/import-from-google-sheets.md](/en/customdata/how-to/import-from-google-sheets.md)

### Large tables and sorting speed-up
**Goal** — registers with hundreds of thousands of rows stay available; speed-up only after explicit confirmation.
- **Speed up sorting** → [./how-to/prepare-sort-index-for-large-table.md](/en/customdata/how-to/prepare-sort-index-for-large-table.md)
- **How it works** → [./explanation/how-large-custom-data-tables-work.md](/en/customdata/explanation/how-large-custom-data-tables-work.md)

## Where to work in the UI

- **Users and roles** module — Custom Data permissions.
- **Menu → Custom Data**:
  - **Custom Data models** → **Trash** — restore / **Delete permanently**
  - **Save view** → **Make shared for everyone**
  - **Model editor** → **Danger zone**
