v1.0.58

Added

• feat: Layout presets — one toolbar control for Single / Columns / Rows / Grid, switchable with Ctrl+Shift+1–4 (⌃⇧1–4 on Mac). Presets auto-balance so N terminals share space evenly.
• feat: Split controls — split the active panel from a tab's hover icons, its right-click menu, or Ctrl+Alt+Arrow (↑ above · ↓ below · ← left · → right). On Mac use Control+Option, not Command.
• feat: Balance panes — right-click a tab → Balance panes to restore even sash sizes after manual dragging (presets already balance themselves).
• feat: Custom layout persistence — manual splits and sash positions are saved in your workspace snapshot and restored after quit or update.
• feat: Terminal mark mode — Ctrl+Shift+M toggles keyboard selection mode (Windows Terminal style). Use arrow keys to move, Shift+Arrow / Shift+Home / Shift+End to select, Ctrl+A to select all scrollback, Enter to copy and exit, Esc to cancel. Shift+nav also extends an existing mouse selection.

Improved

• improvement: Right-hand rails push terminals — clipboard and file preview dock beside the terminal workspace instead of covering it; terminals reflow when a rail opens or resizes (minimum column width preserved on narrow windows).
• improvement: Simpler layout toolbar — removed the separate Split dropdown and Balance button from the toolbar; splitting now lives on tabs and the keyboard, and balancing in the right-click menu, so the toolbar stays uncluttered.
• improvement: Columns and Rows presets now tile one panel per column/row (not just two-way splits) before balancing sizes.
• improvement: Freeform layout mode — manual splits switch to freeform so preset buttons only rebuild when you explicitly pick Single/Columns/Rows/Grid.

Fixed

• fix: Layout shortcuts — Ctrl+Shift+3 (Rows) no longer collides with Ctrl+Shift+D (Dock Satellite), and the digit chords now work regardless of keyboard layout.
