I like to place my terminals on the left and right edges of my screen. Up to like 5 minutes ago, new terminals would open with a y-axis gap between the top of the window and the top of the screen. And they would open at a random x-position. Not any more! I finally learned about the --geometry flag and .desktop defaults to control the way applications launch. Very useful! I might go script some keyboard shortcuts to orchestrate sizing multiple windows simultaneously.
It’s probably worth noting that you specify the width and height of gnome-terminal in rows and columns rather than pixels.
