Open Settings → LastCode → Appearance and enable Larger scrollbars. Two controls appear:
- Scrollbar width sets the visible thumb from 1 px through 12 px in one-pixel increments.
- Scrollbar margin adds 0 px through 6 px of clear space between the thumb and the pane edge.
The default larger-scrollbar profile uses a 10 px thumb and a 4 px margin. That margin keeps the thumb clear of the resize handle between adjacent panes. Changes apply immediately to native app scrollbars, styled scroll areas, and terminal scrollback, and are stored in the current LastCode profile. Turning the setting off restores the standard scrollbar appearance without discarding the chosen width and margin.
LastCode desktop and Chromium-based web browsers apply the exact pixel values to native scrollbars. Firefox exposes only system scrollbar sizes: enabling the setting selects its larger system scrollbar, while the width and margin sliders continue to apply exactly to LastCode's styled scroll areas.
