📝 WalkthroughWalkthroughDesktop and browser preview zoom now use independent paths. New preview webviews start at 100%. Preview shortcuts and menu actions update focused preview zoom, while desktop zoom falls back to the focused main window. ChangesPreview zoom control
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk:🔵 Low · up to The PR is otherwise localized, but an unresolved type mismatch between the serialized preview preference and Electron-side parsing could cause preview zoom settings to be interpreted incorrectly at attach time; merge is reasonable with explicit owner awareness and follow-up.

with a numeric WebContents API call by invoking setZoomFactor(1) after the web
contents is attached, then assert the effective zoom is 1. Update the related
comments in apps/desktop/src/preview/WebviewPreferences.ts at lines 24-32 and

ApprovabilityVerdict: Approved fd96bb0 This is a focused bug fix that decouples preview zoom from app UI zoom. The changes are self-contained to zoom handling, include test coverage for new shortcut detection, and update documentation. The scope is limited with clear intent. You can customize Macroscope's approvability policy. Learn more. |

The View menu now calls This design removes the dependency on focus-mirror state. It avoids both stale focus handoff and listener-install timing issues.
The earlier learning for this PR describes focus/blur routing. The current source-owned design supersedes that learning. Confirm if you want me to remove it. 🧠 Learnings usedYou are interacting with an AI system. |

Manager.test.ts + DesktopApplicationMenu.test.ts + DesktopWindow.test.ts on the PR files: 60/60.
The two coupling points in the body are real on main: a new preview guest inheriting the app renderer zoom, and Electron zoom roles still targeting a previously focused webview. Starting guests at 100% and eating +/-/0 on a focused preview via before-input-event is the right split.
Overlaps #6649 (juliusmarminge, same preview/Manager + DesktopWindow files, opened later). I have not compared the two diffs line-by-line; do not land both.
APPROVED and MERGEABLE.

Note 🤖 GPT-5.6 Sol responding on behalf of Theo Closing this PR after an automated pass over open pull requests. Trusted contributor proposal, but independent preview zoom already shipped in #6649. |
Electron coupled app and integrated-browser zoom in two places: new preview webviews inherited the app renderer's current scale, and Electron's native zoom roles could keep targeting a previously focused preview after focus returned to T3.
New preview guests now start at 100%. A focused preview guest consumes Cmd/Ctrl +
+,-, and0in its ownbefore-input-eventhandler and routes through the same tab-scoped operation as its zoom menu. That prevents the application menu from also handling browser-originated chords. Chords originating anywhere outside the embedded page reach the normal application-menu path, which explicitly zooms the main T3 renderer. Routing is therefore scoped by the exact input source instead of shared or mirrored focus state, and the preview's effective zoom and stored percentage remain synchronized.Validation:

Note
Medium Risk
Changes desktop zoom routing and webview attach behavior; users will see different zoom targets depending on focus, but scope is limited to the desktop preview shell.
Overview
Desktop preview zoom is decoupled from the main T3 UI so app scaling and embedded browser tabs no longer fight each other.
New preview webviews are forced to 100% on attach (
webPreferences.zoomFactor = 1inwill-attach-webview), instead of inheriting the app renderer’s current zoom.When a preview guest has focus, Cmd/Ctrl +
+/-/0are handled inPreviewManagerviagetPreviewZoomShortcutDirectionand the same tab-scopedapplyZoompath used elsewhere (now underwithTabLifecycleLock). Comments on the View menu andzoomMainclarify that native Electron zoom roles are avoided because they can keep targeting a preview guest.Tests cover zoom chord parsing and preview attach zoom; keybindings docs describe independent app vs preview zoom.
