+## Transpose View
+
+Toggle the transpose view to swap rows and columns. This is useful when:
+
+- A table has many columns but few rows
+- You want to compare column metadata (types, defaults, nullable flags) side by side
+- You are inspecting a single row with wide columns
+
+The transpose view preserves all grid features: sorting, filtering, editing, and export work the same way.
+
+## Column Formatters
+
+Custom column formatters let you control how specific column values are displayed:
+
+- **Datetime formatting**: Choose a display format for date and time columns
+- **JSON path extraction**: Extract a specific field from JSON/JSONB columns using a JSONPath expression
+- **Value masking**: Hide or partially mask sensitive values
+- **Custom templates**: Define your own display template for a column
+
+Configure formatters from the column header menu. Formatters only affect display — they do not change the underlying data.
+
+## Cell Detail Editor
+
+The cell detail panel provides a full editor for individual cell values:
+
+- **Value editor**: Edit cell content in a larger text area with syntax highlighting for JSON and SQL
+- **Set NULL**: Explicitly write NULL to a cell
+- **Image preview**: When a cell contains an image URL, the detail panel shows a rendered preview
+- **Temporal editor**: Date and time cells use a dedicated date/time picker
+
+## Multi-Row Operations
+
+Select multiple rows to perform batch operations:
+
+- **Batch clone**: Duplicate multiple rows at once
+- **Batch delete**: Mark multiple rows for deletion in one action
+- **Batch copy**: Copy multiple rows as TSV, CSV, JSON, Markdown, or INSERT statements
+- **Copy as INSERT**: Generate a single `INSERT` statement with multiple value rows
+- **Copy as UPDATE**: Generate `UPDATE` statements for selected rows
+- **Copy without primary keys**: Generate INSERT statements that exclude auto-increment primary keys
+
+## Header Controls
+
+Column headers provide quick access to actions:
+
+- **Sort**: Click to toggle ascending, descending, or clear sort. Right-click for context menu with sort options.
+- **Column visibility**: Show or hide columns from a filterable checklist
+- **Local column filter**: Filter values within the current result set by checking specific values
+- **Compact mode**: When enabled in Settings, header actions (sort, format, filter) collapse into a single dropdown menu, giving column names more space
+- **Compact filter builder**: Build complex client-side filters with multiple conditions in a compact UI

 ## Pagination And Large Results
 
-DBX can page result sets and keep large grids responsive with virtual scrolling. For large tables, prefer database-side `WHERE` and `ORDER BY` clauses instead of relying only on client search, because the database can use indexes and return a smaller result set.
