Safe Auto-Cleanup (Ghost Hunter)
The auto-cleanup script now includes a 3-minute startup delay, error queueing, and a 50-email kill-switch to prevent accidental database deletions during IMAP connection issues.

Ghost File Notification
Users now receive a helpful warning modal suggesting a database rescan when attempting to open a file whose original email can no longer be found.

Responsive Top Navigation
An intermediate responsive layout breakpoint was added to the top navigation bar to smoothly compress paddings and gaps before hiding text labels on smaller screens.

Instant Zen Mode Cache
A smart memory cache was implemented to keep the last 20 viewed high-resolution documents in RAM, allowing for instant, delay-free document switching in Focus View.

Custom Default PDF Zoom
A new setting was added to the dashboard sidebar allowing users to select their preferred default zoom level (e.g., Best Fit, 2/3 Width, Full Width) for opening PDFs.

Seamless PDF Rendering
Artificial loading delays were removed and the layout space for the sidebar is now pre-allocated, preventing any flickering or jumping when opening multi-page PDFs.

Ghost Hunter Upgrade
The cleanup logic now verifies the permanent headerMessageId to correctly identify and remove phantom database entries caused by Thunderbird's ID recycling.

IMAP Timing Fix
A short delay was added before scanning new emails to ensure Thunderbird fully downloads the MIME tree and attachments beforehand.

Endless Loading Resolution
The user interface now properly updates to hide the loading spinner and remove the broken thumbnail when an attachment is marked as deleted by the auto-heal process.

Ghost Tile Eradication
Fixed a persistent memory reference bug where deleted email attachments would reappear as infinitely loading ghost tiles when scrolling through the gallery.

Synchronized Grid Rendering
The visual grid and the internal data state are now perfectly synchronized, ensuring that removed items are instantly and permanently cleared from the interface.

100% Local Privacy
All external image requests, including support buttons, have been completely replaced with local assets to guarantee that no user IP addresses are ever leaked to third-party servers.

Real-time Scan Progress
Restored the live database polling mechanism to accurately display the growing size of attachments during an active scan.

True Scan Cancellation
Clicking the cancel button now actively terminates the background scanning process and instantly loads the files discovered up to that moment.

Improved Empty State
Implemented a user-friendly placeholder message with instructions when the database is empty, preventing the scan modal from aggressively auto-reopening.

Accurate Scan Feedback
Updated the final scan completion message to explicitly state how many "new" attachments were successfully added.

Performance & Event Polling
Resource-heavy interval polling was replaced with native Thunderbird event listeners and bulk IndexedDB transactions for faster background scanning.

Bulk Action Batching
Asynchronous batch processing was introduced for ZIP exports and bulk email actions to prevent UI freezes and memory spikes.

UI Rendering Optimization
Layout thrashing was minimized by bundling DOM read and write operations using requestAnimationFrame and DocumentFragment.

Rename Limit Expansion
The mass rename limit in Review Mode was increased to 999 files with dynamic leading zero-padding.

Zen-Mode Physics & Panning
The missing physics initialization was restored and flexbox margin conflicts were resolved to allow smooth panning of oversized images.

Dark Theme Logo Sync
A CSS mask approach was implemented to ensure the archive SVG logo perfectly inherits the text color across all dark themes.
