A big update covering the last three weeks. The chat interface got a top-to-bottom UX overhaul with a new rich-text prompt editor, slash-command and file-mention chips, and a redesigned tool-call system. The v2 workspace is now in early access, with panes, a diff viewer, a file editor, a review tab, and a browser pane. The Superset CLI shipped and then grew a self-contained tarball that can run the host-service anywhere. The desktop app got a full brand refresh, and GitHub integration is now free on every plan.

Chat UX overhaul #3039

Tiptap prompt input

The prompt is now a ProseMirror-based rich text editor with inline chips for commands and file references.

Slash command chips — type / to open a command menu; the command becomes an inline chip anywhere in the message instead of submitting immediately. Chips with an argumentHint expose an inline editable input with auto-sizing and keyboard nav; /model shows a dropdown of available models.
File mention chips — type @ to open a file-search popover anchored to the cursor. Picking a file inserts a chip that serializes to @path on send.
Skill preload — /command chips are extracted before the LLM turn so the harness loads the right skill first. A SkillToolCall row shows in the message while the skill loads.
Preview on hover — hovering a chip shows a popover with its description (hidden while an arg input is focused).
IME composition guard prevents submit while CJK input is pending; Tab no longer auto-selects commands (Enter or click only).

Redesigned tool calls

Compact, monospaced ToolInput / ToolOutput / ToolHeader layout with a braille spinner and left-side icons
Subagent activity rendered inline as a collapsible tool wrapper, with full markdown for task prompt and response
Clickable file names on every file-related tool call row (read, write, LSP inspect) — clicking opens the file in the editor pane
Syntax-highlighted read-file output with filename header and line-range label; expand/collapse and copy on every code block

ask_user flow

Footer overlay with pinned header/footer and scrollable option buttons — no more inline question UI
Status chips (Awaiting Response / Answered / Cancelled) with a collapsible answer bubble; cancelled shows immediately when aborted
Optimistic dismiss on submit; prompt textarea auto-focuses after answering
ask_user is now required for all Superset questions — no plain-text fallbacks

Workspace status and notifications

A pending question puts an orange dot on the workspace nav and fires a native OS toast, driven server-side through the lifecycle event pipeline so it works when the tab is unfocused
Orange dot clears immediately on answer submit
Auto-scroll to bottom on message send, new question arrival, and answer submit

The v2 workspace is in early access

v2 workspace early access

v2 is a ground-up rebuild of the workspace aimed at cloud. We tore out v1's accumulated cruft, rewrote the terminal from scratch to fix the rendering glitches, and re-architected the app like a real IDE — Tab → Split → Pane, a proper file tree with git decorations, a full editor, and a diff viewer that handles large changesets. Opt-in for now; here's what's in the box:

Pane layout system #3088

A new flexible Tab → Split → Pane structure built on the @superset/panes package, with weighted resizable splits.

Drag and drop panes to rearrange them #3090
Drag to reorder tabs within a tab group #3094
Right-click pane headers for split / close / close others #3196
Double-click a split separator to equalize pane sizes #3101
Cmd+Alt+Arrow moves focus between panes #3403 #3460
Closing the active pane focuses the nearest sibling #3198

Diff viewer #3384

v2 diff viewer

A GitHub-style multi-file diff pane with lazy loading, a persistent "Viewed" state synced to the sidebar Changes list, unified/split view toggles, and header actions for collapse, expand unchanged, copy, and revert. Open it in its own tab with ⌘⇧L #3420 #3556.

File editor #3526

v2 file tree and editor

A full editor pane — foundation, views, and a large stability pass. The file tree shows git decorations inline #3320.

Review tab #3463

PR info, checks, and comments rendered inline in the v2 workspace, matching the v1 review experience.

PR checkout and launch context #3525 #3467

Check out a PR directly from v2 via a widened checkout procedure, and compose a full launch context (selected files, instructions, branch state) before starting work.

Browser pane #3346

Pages stay loaded across tab switches and workspace navigations — no reloads, no lost scroll or form state. URL bar, back/forward/reload, history autocomplete, DevTools, screenshots, and hard reload from the overflow menu.

Git Changes sidebar #3177

A Changes tab in the right sidebar showing ahead/behind status, commit count, and a filterable file list. Filter by all changes, uncommitted only, a single commit, or a commit range. Searchable base-branch picker and inline rename for unpushed branches.

Superset CLI #3194

The superset CLI lets you manage Superset from your terminal, and ships as a self-contained tarball #3298 so you can run the host-service on a remote server, CI box, or cloud VM without the desktop app.

Binaries for macOS (arm64, x64) and Linux x64. --json output mode for scripting and agent use.

Brand refresh #3367

Brand refresh — new logo and icon treatment

New logo and icon treatment across the desktop app, DMG installer background, tray icon, and wordmark. In dev builds, each workspace gets a color-coded corner fold on the dock icon so open workspaces are distinguishable at a glance.

GitHub integration is free #3152

PR review, issue linking, and push-from-desktop are available on every plan — no Pro subscription required.
