Pane number limitation feature

It’s sad for me to default open mutiply panes, after I update to 1.6 version.
I alwasy like to shift + left click a rem to check it in another pane.
I can get a better visual experience in the past, cuz there can be only two panes, the size of each pane is ok to view.
With mutiply pane feature more than 2, I will shift+left click too many panes, or I need to close pane every time after I open a new pane, that’s annoying ::
