Frost Walker Upgrade: Wider Ice Path and Slower Melting Times

I think Frost Walker should get an upgrade that makes it better for both traveling and building. First, a higher tier should freeze a slightly wider path of ice behind you when you walk on water. This would make it much safer to sprint across oceans without accidentally slipping off the edges and falling into the water. Second, the ice created by Frost Walker shouldn't melt instantly during the day. If it melted slowly over time instead, players could use the ice paths as temporary scaffolding to build permanent bridges across water without having to constantly swim or recreate the ice.
