Height of tracks

Hi everyone,
i’m using desktop version (n-track 9.1.4) . When i create a new track, MIDI or audio, the height of this track is fullscreen.
I know that there is a button to minimize that or to resize but when i have to expand the track, it returns to fullscreen.
Is there a way to set a default height for all the tracks?
Thank you.

The height of tracks depends on the zoom level. You can change the vertical zoom with the +/- buttons in the bottom right part of the timeline (at the bottom of the vertical scrollbar) or using the mouse wheel with the Ctrl+Shift keys pressed.
