I hate the embedded terminal personally and just use a "real" one in its own window.

Or even better — Right click on the terminal panel label and select the option to move it into the editor area.

The editor area has far more flexibility. Your terminal can be almost any size and you can have multiple terminals visible at once or a tab click away. If you need it to be larger you can drag the tab elsewhere to make it big without rearranging your window.

I also keep a terminal (or three) open permanently, but it's usually tiny - around 1500x400 pixels (that is tiny on my very large screen). Sometimes I'll move the terminal into a larger editor panel (which is about 5x that size).

Good tip, but I like it at the bottom. I prefer to have 2 or 3 file columns so I am more limited by horizontal space. If I need to see two parts of the same file I can just open it in two different columns.
