Features

• Flying bypass: fly over buildings at the same speed as when walking on the ground
• Slow standstill: you can start slow and build up your speed
• Zoom-based cap: you can cap your speed according to zoom level
• Acceleration & deceleration: can be used to make walking speed changes smoother and less jarring

Compatibility

It probably won't work correctly with mods that change the character running speed modifier; let me know if you run into issues. Mods that add equipment with movement speed bonuses should be fine.
