I tend to split panes by functional role, so for example in one pane I might be jumping through view code while in the other I might be working with view models. It’s not helpful to bounce me up and down the editing history of the view model file to the right when the intention is to quickly jump though view file history on the left (or vice versa).

The best thing to do would be to make it a checkbox, like IntelliJ does for almost everything else, but not that for some reason.
