 - **Library (Files) tab:** upload up to **2 GiB per file**. Files are encrypted and stored in the hub's own object storage. The old 20 MiB limit and the separate Drive tab are gone — the Library replaces both.
 - **Compose:** attach up to **4 images or videos** per post (10 MiB per image, 64 MiB per video) and add **alt text** descriptions — they appear on Mastodon.
 - **Video producer:** apply **lower-third, logo, or clock overlays** and **voiceover** to any library video. Clips with no audio get a synthesized silence bed, so they always work. Results land back in the library and can be published like any other asset.
-- **Large videos:** uploads are automatically split into 10 MB chunks — big files work even through Cloudflare.
+- **Large videos:** uploads are automatically split into 10 MB chunks — big files work even through Cloudflare. When direct storage is enabled, files upload encrypted straight to object storage without passing through the server at all.
+- **View everything in-app:** photos open in a lightbox (zoom, pan, rotate), videos play in the hub's own player (scrubber, speed, PiP, fullscreen, keyboard shortcuts), PDFs open in place, text files are readable with one-click copy, and HTML files run in a sandboxed preview.
+- **Edit photos:** crop (free, 1:1, 16:9, 9:16), rotate, flip and adjust brightness/contrast/saturation — saving creates a new file, the original is never modified.
+- **Trim videos:** set start and end points and send the cut to the Video Studio — the cut renders as a new clip in the Video library.
+- **Upload several files at once:** drop or pick multiple files — each uploads in turn with its own progress, and one failure never blocks the rest.
