Interactive preview

The grug window is split in half the left side is the search box the right side is the buffer I was in when I opened grug. I think it is better if the right side changes when I change my place in the left side, like interactive preview like vscode. The right side can be empty when you open grug or can be on the first search result. If I type enter on a result it can move my cursor to the preview buffer on the right side.
