✨ [feature] Desktop UI modernization: Flat, borderless design by iotserver24 · Pull Request #92 · iotserver24/Xibecode

iotserver24 · 2026-05-17T05:48:25Z

🎯 What: Redesigned the desktop React UI to match the modern, minimalist, dark-themed, and borderless design language common in leading AI assistants like Claude Desktop and Cursor.

💡 Why: The previous UI had excessive subtle borders (border-xibe-border-subtle), prominent outlines on inputs, and distinct container boundaries that made it look slightly segmented. A flatter design improves modern aesthetic appeal.

✅ Verification: Verified visually using a Playwright script targeting the local Vite dev server. The resulting screenshots show a unified layout without harsh dividing lines, elevated solid action buttons, and flat input controls. Also passed the full workspace test suite to ensure no logic regressions.

✨ Result: A sleeker, modern UI interface for the desktop app.

Summary by CodeRabbit

Style
- Updated visual styling across the desktop interface, including removal of borders on key UI regions.
- Refined button appearance for mode selection and quick-action controls.
- Adjusted message bubble styling for improved visual consistency.
- Refined color palette for surfaces and borders throughout the application.

- Replaced outlined borders with filled surfaces across main sections (headers, sidebars, panels). - Updated ChatPanel components (action buttons, chat input container, mode selectors) to use `bg-xibe-surface-raised` borderless styles. - Updated user message bubbles and inline code blocks in MessageBubble.tsx to use borderless flatter backgrounds. - Updated Tailwind config variables in `global.css` to blend sub-surfaces better for a seamless look.

📝 Walkthrough

Walkthrough

This PR applies a cohesive visual refresh to the desktop renderer's styling by darkening theme color tokens, removing decorative borders from the main layout structure, and refining interactive component and message rendering styles to achieve a flatter, more minimal appearance.

Changes

Desktop UI styling refresh

Layer / File(s)	Summary
Theme color palette darkening `packages/desktop/src/renderer/styles/global.css`	The `@theme` variables for raised surfaces and borders are darkened from `#27272a` to `#18181b`, establishing a darker palette for the subsequent component styling updates.
Layout structure border removal `packages/desktop/src/renderer/App.tsx`	The header, left sidebar, and right sidebar containers drop their subtle border styling while retaining all layout behavior, transitions, and overflow handling.
ChatPanel button and input styling `packages/desktop/src/renderer/components/ChatPanel.tsx`	Mode selection buttons toggle between raised and dim styles, quick-action buttons switch to raised borderless styling, and the floating input container removes explicit borders in favor of raised surface backgrounds.
MessageBubble and markdown code rendering `packages/desktop/src/renderer/components/MessageBubble.tsx`	User message bubbles adopt raised surface backgrounds with rounded corners; assistant message Markdown code renderers update to use non-raised surface backgrounds with refined prose styling.

🐰 Borders fade away like morning dew,
Surfaces raised and darkened through,
The UI breathes, now flat and clean,
A minimalist dream on every screen! ✨
