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.
