[FEATURE] JetBrains plugin: setting to disable diff auto-focus / tab-switch (accessibility)

Problem Statement

When using the JetBrains Claude Code [Beta] plugin with diff_tool in its default IDE mode, the plugin auto-focuses the
diff view and switches the active editor tab to the file being diffed whenever Claude edits a file. There is currently
no plugin setting, /config option, settings.json key, or IDE registry flag to suppress this while keeping IDE diffs
enabled.

Accessibility impact

I have ASD. Involuntary focus/tab-switching isn't a preference issue — it removes control over where my attention goes,
which is a documented accessibility barrier:

• WCAG 2.4.3 (Focus Order) — focus must move in an order that preserves meaning and operability.
• WCAG 3.2.1 (On Focus) — a change of context must not occur solely from a component receiving focus.

The JetBrains platform already exposes the primitive (focusEditor=false on FileEditorManager.openFile(...) and
similar APIs). The plugin just needs to surface it.

Proposed Solution

Any one of these would fix the problem:

1. A JetBrains plugin setting in Settings → Tools → Claude Code [Beta]: "Open diffs without stealing focus / switching

tab" (checkbox).

1. A Claude Code config key (e.g. diffAutoFocus: false) that the plugin reads and uses to pass focusEditor=false to

the IDE's file-open API.

1. Respect the existing prefersReducedMotion setting from ~/.claude/settings.json as a signal to suppress focus

changes as well as animations — this already has accessibility precedent in the schema.

Alternative Solutions

Alternative Solutions

• Set diff_tool to terminal via /config. Works but eliminates inline IDE diffs entirely, which is a significant

ergonomics downgrade. The accessibility fix shouldn't require giving up the feature.

Use Case Example

While reviewing output in one tab, Claude edits a file in another part of the project. The JetBrains plugin yanks the
editor to that file's diff view, breaking my concentration and forcing me to navigate back to where I was. With many
edits in sequence, the effect compounds.
