Adds two tiny arrow buttons to each colonist's row in the Schedule tab, right after Copy/Paste. Left arrow shifts the whole 24-hour schedule one hour earlier, right arrow — one hour later. Cyclic, per-colonist.
Modifiers:
- Shift+click — shift by 6 hours (quarter-day block)
- Ctrl+click — shift by 12 hours
Works in 1.5 and 1.6. Requires Harmony.
