Changelog

Fix default shell selection, directory tracking in auto mode splits, and agent process reconstruction

• — Fix default shell profile synchronization in palette and settings menu
• — Fix auto mode panel splits to accurately preserve active agent (Antigravity, Claude, Codex) and working directory
• — Fix foreground process resolution in ConPTY to detect shell return when child processes exit

Built-in modal code editor with real navigation and clipboard, GPU Quick Peek previews for directories, SQLite, and CSVs, 3D wireframe inspector, and async git diffs in agent alerts.

• — NEW In-Terminal Modal Code Editor: Full modal editor and inspector right inside the terminal. Click any file or press Enter from Quick Peek to edit code with syntax highlighting, line numbers, word jumps (Ctrl+Left/Right), mouse selection (double/triple-click), system clipboard (Ctrl+C/V/X), and instant Ctrl+S saving.
• — NEW GPU Quick Peek Previews: Instant hover cards for terminal paths: browse directories with Nerd Font icons, inspect SQLite database schemas, read auto-aligned CSV tables, and view binary hex dumps.
• — UI Interactive 3D Turntable & Media Viewer: Orbit around .obj 3D meshes with interactive mouse pitch/yaw, zoom, and auto-rotation; pan and zoom images smoothly; and launch binaries in their default system apps.
• — UI Tab Picker & Fluid Transitions: Polished spring kinematics and card geometry across the visual Tab Picker, preserving live frames without blank previews or stutter during workspace transitions.
• — NEW Async Git Diff in Agent Alerts: Background AI agent notifications (Claude Code, Antigravity, Cursor) now display async git diff stats (+/- line counts and touched files).
• — UI Native OS Interop & Explorer: One-click action to jump into Windows Explorer from directory views, natural wheel zoom direction, and aligned modal styling with active themes.
• — FIX Loop & Clipping Fixes: Eliminated an infinite loop in editor line layout, fixed card border clipping on high-DPI scaling, and replaced placeholder glyphs with vector Phosphor icons.

Split animations without dropped frames, native Phosphor vector icons across the entire UI, asynchronous process snapshots, and low-latency remote streaming.

• — PERF Silky 144Hz Split Animations: Offloaded blocking ConPTY Resize calls to background worker threads. Windows no longer stalls the render loop during pane splits and resizes.
• — PERF Zero-Spike Grid Allocation: Pane resizing in background grids is now budgeted across frames, preventing micro-stutters when manipulating complex multi-pane layouts.
• — PERF Asynchronous Process Snapshots: Foreground process inspection for tab titles runs completely in the background, eliminating main-thread hiccups under heavy system load.
• — UI Phosphor Vector Icons: Embedded native Phosphor vector icons directly into the binary, replacing ASCII hacks (x, w, <, >, +, v) with razor-sharp glyphs on all UI surfaces.
• — UI Niri-Style Elastic Transitions: Polished spring kinematics and card geometry across the Tab Picker and workspace transitions for fluid, natural movement.
• — NEW Asynchronous Remote Streaming: Real-time ring-buffered streaming pipeline in pexerd that drastically reduces latency without relying on heavy snapshot RPCs.
• — NEW Instant Snap-Splits & VSync Toggle: Configurable VSync option and optional zero-animation snap-splits mode for instant tiling at native display refresh rates.

A massive leap under the hood: a standalone background daemon server to keep sessions alive even if the app closes, zero-perceived-latency remote typing with predictive echo, near 0 MB RAM footprint in sleep mode, animated Shadertoy backgrounds on DirectX 11, and a living Tab Picker with persistent previews.

• — BREAKING CRITICAL NOTICE: Remote sessions are still HEAVILY EXPERIMENTAL. Truncated or cut-off scrollback in remote panes is 100% NORMAL and expected in this build while we finalize Protocol v2 pagination.
• — NEW Persistent Background Server (pexerd for Linux & Windows): Terminals are no longer tied to the GUI window. A standalone daemon with shared memory keeps your shells, builds, and agents running in the background even if Pexer closes, crashes, or reboots.
• — PERF Speculative Local Echo (0ms Remote Typing): Remote latency eliminated. Keystrokes render instantly on your GPU at your display's native refresh rate with automatic rollback if the server diverges. Includes automatic password masking for secret inputs.
• — PERF Remote Protocol v2 & Wire Optimizations: SIMD-accelerated delta compression, 32-bit RGBA TrueColor fidelity, clean alternate-screen isolation (no ghost text from Neovim/clear), and asynchronous streaming proxy.
• — PERF Zero-RAM Background Sleep: Minimizing or closing to the Windows tray automatically freezes idle processes, purges DirectX 11 swapchains, and drops working set memory down to near 0 MB in RAM.
• — UI Visual Tab Picker with Living Previews: Replaced boring text lists with live native thumbnail cards that preserve your last active frame—no more empty black boxes after clear or waking up.
• — NEW Smart State Tags & Tab Autocomplete: Filter panes on the fly with @working, @blocked, @idle, @agent, or @remote. Includes instant Tab autocompletion and clickable filter chips.
• — NEW Shadertoy GPU Backgrounds (Direct3D 11): Real-time GLSL-to-HLSL transpiler supporting standard uniforms and theme colors. Drop .glsl shaders into %APPDATA%\Pexer\shaders with instant hot reloading.
• — NEW IPC Window Controller (pexerctl): Control splits, zoom, focus, and workspaces programmatically via high-speed named pipes (\\.\pipe\pexer-gui).
• — NEW Agent Lifecycle Awareness: Real-time detection and state indicators for AI coding tools including Claude Code, Antigravity, Codex, Cursor, Gemini, and more.

High-fidelity UI & font rendering, linear DirectWrite blending, and opt-in diagnostic logging.

• — NEW Opt-in diagnostic logging & ConPTY tracing for deep session diagnostics
• — PERF Linear DirectWrite blending and crisp font coverage at sub-pixel levels
• — FIX Fixed D3D11 outline shader and hairline borders at fractional DPI scaling
• — UI Continuous active tab geometry without visible rendering seams
• — UI Robust font family resolution with 256-font picker capacity
• — UI Dynamic command palette footer layout with adaptive keyboard shortcut badges

A cleaner About experience with a reliable, readable bundled license viewer.

• — UI Redesigned the About dialog with a compact layout and clearer actions.
• — NEW Added a complete viewer for all 7 bundled component licenses.
• — FIX Fixed invisible labels, navigation, scrolling, and button rendering in license view.
• — DOCS Added the Built with love by NeonDeex credit.

Smoother workspace, pane, and cursor animations.

• — PERF Refines spring-driven workspace and pane transitions for consistent motion.
• — UI Improves tab dragging and reorder feedback while keeping panes aligned during movement.
• — UI Polishes cursor and interface animation behavior across terminal controls.

First public alpha of Pexer, a small native terminal for Windows 11.

• — NEW Runs as a native Windows 11 x64 application in one portable executable.
• — PERF Uses Direct3D 11 for hardware-accelerated text rendering and smooth window updates.
• — NEW Supports ConPTY, Unicode, scrollback, text selection, and smooth terminal resizing.
• — UI Supports tabs plus horizontal and vertical split panes.

• — UI Includes a 3D wheel for switching between workspaces and projects.
• — NEW Activity and attention indicators for Claude Code, Codex, Antigravity, Cursor, and Gemini.
• — NEW Keyboard-friendly command palette with fuzzy search.
