Stack Deletion Fix: Resolved an issue where newly created stacks could not be deleted. Confirmation dialogs now trigger smoothly and empty stacks provide direct action buttons.
Firefox Sync Notification Fix: Eliminated the false-positive "Synced from another device via Firefox Account" notification that was appearing on every new tab open. Sync notifications now only trigger when newer data is genuinely pulled from another device.
Quick Header Controls: Added quick hover actions to stack headers for adding links, renaming, or deleting stacks without needing to toggle full edit mode.

• Sub-16ms Instant Pre-Hydration: The new tab now renders immediately on Frame 0 directly from local storage. Eliminated the ~0.5s initialization delay previously caused by sequential asynchronous extension storage calls.
• Non-blocking Background Sync: Firefox Sync and background verification now run completely asynchronously without blocking the UI or delaying initial paint.

• Dead-Center All-Sides Alignment: Perfectly balanced vertical and horizontal centering across all screen sizes and resolutions.
• Faded Minimalist Action Button: The bottom-right + trigger button is now subtle and translucent (opacity: 0.28) by default, smoothly fading into full focus on hover to maintain maximum minimalism.
• Row-Consistent 3-Column Grid: Restored pure CSS Grid for stacks, eliminating masonry-like column flows. Stacks in Row 1 and Row 2 maintain clean, aligned horizontal baselines regardless of individual card heights.
• Zero Page Shift on Collapse/Expand: The stage position is locked during accordion toggles with scrollbar-gutter: stable, guaranteeing 0px movement of the search bar, daily apps shelf, or page.

• Edit Stacks Button: Fixed a double event listener conflict that caused edit mode to immediately exit on click. Clicking "Edit Stacks" now enters and remains in edit mode until you're done editing.
• Search Escape Key Layout: Fixed a layout corruption bug where pressing Escape to dismiss search collapsed the dashboard into a single column. The 3-column grid now restores seamlessly.
• Keyboard Navigation: Improved Escape key handling to reliably blur search, clear input text, and hide results dropdowns.
• Comprehensive Function Audit: Verified all buttons, modals (New Stack, Add App, Preferences, Shortcuts, Link Inspector), and dynamic light/dark theme switching.

What's New in TabStack 1.0.1:
• Fixed stacks not being draggable
• Collapsible Stacks: Click any stack chevron or title to tuck it away and save space; stacks below smoothly glide up with no empty gaps.
• Speed Dial Controls: Bottom-right controls remodeled into an authentic GNOME Libadwaita Floating Action Button (FAB) menu.
• Firefox Account Sync: Seamlessly sync stacks, apps, card order, theme, and accent colors across your machines via Firefox Sync.
• Refined UI: Polished button aesthetics, single-line alignment, and authentic GNOME HIG transitions.
