Eclipse navigator opened file in other sub-window -


i messed eclipse's navigator configuration. in default settings when open/double click file in navigator, open in window in picture 1. , now, altered (undesired) behavior makes eclipse open new tab in same window, hiding navigator tab (picture 2).

default configuration

file opened

i'd revert default behavior in picture 1. how do this?

i'm using mars.2 release (4.5.2)

it seems using top menu window > prespective > reset perspective works.
