v3.0.0

Release Notes — v3.0.0

Version 3 introduces a leader-key system based on the g and z prefixes. This enables most keyboard shortcuts to be remapped for broad compatibility with VisiData while remaining fully customizable through the Commands tab. User-defined bindings can be saved to a JSON config file and loaded on startup.Please review the updated key bindings and the many new features described in the README.

✨ New Features

Sheets Overview (S)

• Press S to open a SheetScreen modal listing all open tabs with tab name, loaded rows, total rows, column count, and source filename.
• Press Enter to jump to a tab, e to rename it, d to close it — all from the sheet list.

Join Tables (&)

• Join two open tabs into a new tab using SQL-style joins (inner, left, right, cross) with column alignment support.

Inline Bar Charts (z=)

• Toggle an inline bar chart for any numeric column directly in the table view.

Pin Column (!)

• Pin the current column to the start of the table.

Column Resize (z_)

• Resize the current column to a specific character width.

Fill Null Values (zf / gf)

• Fill null values in the current column (zf) or all columns (gf) with a user-provided value. Input widget respects the column's data type.

Global Cursor Search (;)

• Search the entire dataframe for the current cursor value, highlight all matches, and jump to the first one.

Last-Tab Jump (zB)

• Jump back to the previously focused tab.

Implode Column (z))

• Collapse rows by aggregating a column into a list, respecting selected columns as group keys. The imploded column now replaces the original column in-place.

Row Selection Expansion (gs / zs)

• Select the current row and all rows above (gs) or below (zs).

Column Selection Expansion (g' / z')

• Select the current column and all columns to the left (g') or right (z').

Unselect Rows (gu)

• Toggle the selection of the current row (s) or unselect all selected rows (gu).

Delete Column Range (g* / z*)

• Delete the current column and all before it (g*) or all after it (z*).

Cast to Boolean (z#)

• Cast the current column to boolean type.

Set Row as Header (g^)

• Mark the current row as the new column header row.

🔧 Improvements

• Per-column thousand separator (z,): Toggle number formatting independently per column (previously global).
• Per-column float precision (< / >): Adjust decimal places per float column independently.
• Strip whitespace (zSpace): Strip leading/trailing whitespace from string columns.
• Page forward/backward now moves the cursor and preloads row batches correctly.
• Find & Replace: Enhanced search commands with cursor-value shortcuts (z/, z?) and global search (;).
• Row detail modal: { / } navigate between rows; frequency and statistics accessible directly from row detail.
• Frequency distribution now supports multiple selected columns.
• Statistics screen applies highlight styling for selected rows.
• EditCellScreen supports list-type values.
• BusyScreen now wraps background tasks with a decorator pattern.
• Python console moved to table-level (Space to toggle); gSpace runs a command by name.
• Keybinding conflicts are detected and logged at startup; user config overrides are loaded from ~/.config/dataframe_textual/keybindings.json.
• Numerous notification messages refined for clarity and consistency.
