Staircase 0.1.13 — the chat's connection status is a small indicator in the top bar (a green dot when connected; soft Connecting / Syncing / Reconnecting; Offline only after 30 s) instead of a red strip, with plain-language details on tap. Messages sent while offline wait and go out by themselves once the chat reconnects. Desktop: one themed message menu with Copy selection / Select all text. Multi-device catch-up fetches missed messages while reading the other device's documents and brings 8 groups up to date at once.
