You can hide all the tool window bars if you need more space in the IntelliJ IDEA window:
- In the lower left corner of the workspace, click
.
If the tool window bars are hidden, you can bring them back onto the screen either permanently or for a short period of time:
- To restore the tool window bars, click
in the lower left corner of the workspace.
- To see the tool window bars for a short period of time, double-press and hold the AltCommand key. The tool window bars appear on the screen making the tool window buttons accessible. The tool window bars are hidden again when you release the key.
- Drag-and-drop the corresponding tool window button onto the desired tool window bar.

- Right-click the corresponding tool window button or the tool window title bar to open the context menu.
Choose and then select the destination tool window bar (Top, Left,

The obvious way to resize a tool window is this:
- Hover the mouse pointer over the tool window border. When the pointer becomes a double-headed arrow,
drag the border in the required direction.

You can also resize a tool window by moving its border to left or right, or up or down in steps. The following alternatives are available for doing that:
- Right-click the corresponding tool window button or title bar and select Resize. Then select one of the available Stretch to options.
- Make the tool window of interest active and do one of the following:
- Choose , and then select the necessary Stretch to option.
- Press Ctrl+ShiftCtrl Shift in combination with the corresponding arrow key.
To increase the maximum number of tool windows to be shown at a time, you should appropriately set the viewing modes for different tool windows. Consider the following:
- Generally, for a tool window to be visible always (i.e. even when inactive), the tool window should be pinned.
- There are no limiting factors for the number of floating windows shown simultaneously.
- To be able to see two windows docked to the same tool window bar at a time (rather than one), one of the windows should have the split mode off and the other one on.
- Initially, three (out of four) tool window bars are used. You can "activate" the forth tool window bar (the top one) by moving certain tool windows to it.
