Smooth scrolling

Scroll the UI smoothly, pixel-by-pixel, instead of line-by-line.

This also enables animated smooth scrolling for Windows and Linux by default. You can disable it to use precise scrolling instead: press Control+Shift+A, find and open the Smooth Scroll Options dialog, and disable the Animated smooth scrolling checkbox.

In this dialog, you can also set the duration of the scroll animation and change the appearance of the animation based on https://cubic-bezier.com/#.17,.67,.83,.67.

Drag-and-drop with Alt pressed only

Avoid accidentally moving files, editor tabs, tool window buttons, and other UI components. When enabled, hold the Alt key to move things around.

By default, this option is disabled and you can move everything without any extra keys.

Show icons to the left of the items in the main menu and context menus.

Background Image…

Configure a custom background image for the IDE.

IDE

Select which antialiasing mode you want to apply to the IDE (including menus, tool windows, and so on):

• Subpixel: this option is recommended for LCD displays and takes advantage of the fact that each pixel on a color LCD is composed of red, green and blue sub-pixels. This allows smoothing text and rendering it with greater detail.

• Greyscale: this option is recommended for non-LCD displays or displays positioned vertically. It deals with text at the pixel level.

• No antialiasing: this option can be used for displays with high resolution, where non-antialiased fonts are rendered faster and may look better.

Editor

Select which antialiasing mode you want to apply to the editor:

• Subpixel: this option is recommended for LCD displays and takes advantage of the fact that each pixel on a color LCD is composed of red, green and blue sub-pixels. This allows smoothing text and rendering it with greater detail.

• Greyscale: this option is recommended for non-LCD displays or displays positioned vertically. It deals with text at the pixel level.

• No antialiasing: this option can be used for displays with high resolution, where non-antialiased fonts are rendered faster and may look better.

Remember size for each tool window

Remember individual width of every tool window when you reopen or switch between them.

When this option is disabled, tool windows have the unified default width, and their sizes remain constant when you switch between them.

This feature is not available in the new UI.

You can hold the Alt key and press the corresponding number key to switch tool windows regardless of this setting: Alt+1 for the Project tool window, and so on.
