package: x2goclient version: 4.1.2.1
To create a new subfolder, you curently need to click on the three dots "..." next to the path in the session configuration, then right-click the folder under which you want to create the new folder. There's no hint that you need to do so, and the only buttons are OK and cancel.
But wait, the weirdness continues: The right-click menu only offers a "create new folder" option (when used on the root folder). When you click that, it creates a folder named "new folder". It doesn't prompt you for a name. The only way to set a name is to right-click the newly created folder again, because this time, the menu contains a rename option.
