✅ Folders inside folders — every folder's ≡ menu now has Create folder, so you can build a tree of any depth to organize your chats. Subfolders sit above the chats inside a folder, each with its own New chat / Rename / Delete actions, and Move to… shows the whole tree, so a subfolder is a valid destination like any other. Keep as many branches open at once as you like, at any depth; closing a folder hides everything inside it, and deleting one clears its whole branch after a clear warning.

✅ Folders work the same on your phone — tapping a folder in the Dialogs sheet opens it right there, so you can walk down a nested tree without the sheet closing on you. It closes when you actually go somewhere: tapping a chat, or picking New chat in a folder's ≡ menu — which starts the chat inside that folder.

✅ Seedance 2.5 joins Image → Video — a new model for animating a photo, with durations from 4 up to 30 seconds (4, 5, 6, 8, 10, 15, 20, 30) — the same 30-second ceiling Wan 3.0 and Wan 3.0 Prime already offer. It is the premium choice in that menu: noticeably more per second than the rest, so a long clip is a real spend. As always the per-second rate is in Pricing and the cost of your clip is shown before you run it.

✅ The app tells you when a big update is out — if a major MF0.ai update ships while your tab stays open, a popup in your language names the new version, and one click on OK refreshes you onto it. Only for real releases: the constant small fixes never interrupt you.

✅ Around the app — after reusing an older request (the ↻ button), the composer's model pill always shows the restored model; and the rename-conversation window now speaks all 11 interface languages.
