power-kit-entry-badge

name	power-kit-entry-badge
description	Configure and display the notification badge (small red dot) on the Power Kit entry button in the Gemini sidebar. Use when adding new feature announcements, bumping badge version to re-show for all users, or adjusting badge display modes (icon corner vs inline after text).

Power Kit Entry Badge

Files

• src/entrypoints/content/power-kit-entry/badge.ts — storage state (read/dismiss)
• src/entrypoints/content/power-kit-entry/index.ts — DOM injection & display logic

Re-enable the badge after a new feature release

Increment POWER_KIT_BADGE_VERSION in badge.ts:

// badge.ts
export const POWER_KIT_BADGE_VERSION = '2'  // was '1'

All users (including those who dismissed) will see the dot again on next page load.

Display modes

The badge supports two modes depending on the sidebar state (DesktopVariant):

State	Mode	Appearance
collapsed	icon	Red dot at top-right of mat-icon (position: absolute; top: -3px; right: -3px)
expanded	inline	Red dot appended after label text (display: inline-block; margin-left: 6px)

The mode is set automatically in decorateDesktopEntry based on variant. Mobile always uses icon mode.

CSS selectors

/* Collapsed state — icon badge */
[data-gpk-badge="icon"] { position: absolute; top: -3px; right: -3px; ... }

/* Expanded state — inline after text */
[data-gpk-badge="inline"] { display: inline-block; margin-left: 6px; ... }

CSS is injected once via injectBadgeStyle() (idempotent, keyed by #gpk-badge-style).

State management

shouldShowBadge()  // checks storage.local['powerKitBadgeSeenVersion'] !== POWER_KIT_BADGE_VERSION
dismissBadge()     // writes current version to storage

badgeVisible (module-level boolean) is set asynchronously at bootstrap and drives all ensureBadgeDot calls. Clicking the button sets badgeVisible = false, removes all dots, and calls dismissBadge().

Bootstrap flow

shouldShowBadge().then((show) => {
  badgeVisible = show
  if (show) {
    injectBadgeStyle()
    syncEntries()   // re-decorates existing entries to inject dot
  }
})
