Background download improvements: compact, collapsed task cards highlight file saving status, with title links opening the original post in a new tab. Adds save-status and creation-date filters, per-task and global batch saving, and an option to stop remaining downloads. Fixes inconsistent newest-first ordering. Android reuses the existing task tab without switching focus, distinguishes requested downloads from confirmed saves, and retains per-file retry controls. Desktop manual saves now wait for download completion before releasing cached files. Android may require confirmation for each file; keep the task page open during batch saving.

Media downloads, frames, collages and cards now run as background tasks, independent of the original post tab after queue confirmation. Desktop saves automatically; Android uses a separate task page for manual saving. Adds opt-in experimental FFmpeg video/GIF framing and animated collages, configurable limits, a time estimator and diagnostics. Saved desktop media caches are released immediately; Android retains saved files for 24 hours and unsaved files for 7 days. Diagnostics expire after 7 days and finished tasks after 30 days. Media and diagnostics are stored separately to reduce I/O. Source archives remain user-managed.

Adds horizontal media stitching and single-row post cards, with seamless or gallery spacing and the selected source-frame position. Introduces a compact mobile sheet with collapsed previews and pinned actions. Adds English localization and language selectors in the popup and settings. GIFs and videos use still previews in stitched images and cards; save original media to preserve animation.
