How to open two terminal windows in IntelliJ IDEA, PyCharm?

Besides the great answer given by avb (using the + or right click), you can of course also use a hotkey for this (when selected the terminal) press:

MacOs: Command+T / ⌘T

Windows / Linux: Ctrl + T

Note: you can even rename tabs by double clicking on their label.

In case of terminal toolbar status, you can do one of these options

Also after that you can drag them as tabs and let them be side by side.

You can open multiple tabs and then use the mouse drag them out into the editor area. Then you may want to split the editor vertically to have two consoles side by side. Or you could use one terminal in the tool window and the other up in the editor area.

This worked for me in IntelliJ Idea...

Click the plus icon to open a second terminal window

If you want to split the windows so both shows at the same time, just right-click on the second tab and select horizontal or vertical

Hope it helped someone.
