v0.9.0-beta.1

Added

• #32 — Auto-save (Settings → Auto-save changes, on by default): edits save themselves a few seconds after each change, and switching floors saves first instead of asking to discard. Refreshing or closing the tab with unsaved changes now asks before leaving. Reset floor/property and remove all devices still wait for you to press Save, so an accidental reset isn't committed.
• #33 — Draggable room labels: select a room, then drag its name somewhere more readable; Reset label position in the room's panel puts it back.

Changed

• #33 — Room labels now sit at the most open spot inside the room by default, instead of the average of its corners — L- and U-shaped rooms no longer get their name on or behind an inner wall.

Fixed

• An edit made while a save was in progress could be marked as saved when it wasn't.
