Mono

Neutral gray themes for Paseo: Mono Dark and Mono Light. Backgrounds, surfaces, borders, and text use distinct gray levels; accent, selection, and focus use the foreground color. Paseo retains semantic status colors for success, warning, and danger.

Requires Paseo >= 0.9.0.

The layout tweaks below are independent of the theme: they work with any theme, and you can use the Mono themes without them.

On desktop and web, Mono condenses the top sidebar navigation — New workspace, History, Search, Schedules, and any plugin sidebar items — into one icon-only row that follows your configured order. Hovering an icon shows its name; native buttons and accessibility labels remain intact. The composer's dictation and voice-mode buttons are hidden as well (keyboard shortcuts still work). The context ring is hidden while it has no context data. The divider lines at the top and bottom of the left sidebar, above and below the footer Usage summary, at the top of the Explorer, under the center header and tabs, and between the sidebar, center, and Explorer are removed (resizing still works). The composer and the pills above it drop their outlines too, and popover menus keep only a hairline border at 50% opacity (tinted from the Mono palette when a Mono theme is selected, or from the current theme otherwise).

On desktop and web, file attachments in the composer show a file-type mark and filename, sized to match the composer's input text. Hover or click a workspace file attachment to see its path; long paths keep their first directory and filename, and the full path remains available in the hover tooltip.

On every platform, Mono also hides agent Thinking rows from the timeline (via an official timeline transformer). Tool calls and messages are unchanged.

Each tweak is on by default and can be toggled in Settings → Plugins → mono → Settings: compact sidebar navigation, hide dividers and borders, hide Thinking, optimize Composer file attachments, hide the empty context meter, hide the dictation button, and hide the voice mode button. Settings are shared by every client of the same host.

On desktop and web (any theme), each model in Settings → Providers → provider gets a switch. Turning it off hides that model from the composer model picker and the new-agent model list; turn it back on to restore it. Provider rows in the picker count only visible models. The currently selected model and agent profiles are unaffected.

Palettes live in shared/palette.ts; Paseo expands each 8-color palette into the full token set. The disposable Web DOM adapters live in client/web.ts and client/model-visibility-web.ts and use Paseo's semantic test IDs rather than visible labels. Specs are in specs/.
