IntelliJ IDEA Appearance and UI Settings Guide

1. Appearance

Set the IDEA theme and font. Enable Sync with OS to synchronize system changes. Check Use custom font to choose the code font and size.

2. Accessibility

Enable screen reader support, increase scrollbar contrast, and adjust colors for red‑green color deficiency, which also changes the colors of highlighted code fragments and progress bars.

3. UI Options

Show tree indent guides to visualize project hierarchy. Enable smooth scrolling for more fluid mouse wheel navigation. Use smaller indents in tree menus. Enable Alt‑drag‑and‑drop to prevent accidental moves. Activate mnemonics in menus and controls. Merge the main menu into the window title. Show icons in menu items. Adjust the IDE background image.

4. Antialiasing

Select antialiasing mode for the IDE and editor: Subpixel (for LCDs), Greyscale (for non‑LCD displays), or No antialiasing (for high‑resolution screens).

5. Tool Windows

Show tool window bars, numbers, and configure side‑by‑side layouts on the left or right, as well as widescreen layout to maximize vertical space.

6. Presentation Mode

Adjust the font size used in presentation mode.

2. Menus and Toolbars

Customize menus and toolbars to include only needed actions, rearrange them, and set custom icons (PNG or SVG).

3. System Settings

1. Passwords

IntelliJ IDEA can store passwords for VCS, databases, and other protected resources. Options include using KeePass, encrypting the master password with a PGP key, or not saving passwords at all.

2. HTTP Proxy

Configure proxy settings for Internet access (HTTP/HTTPS). Options: No proxy, Auto‑detect, or Manual configuration.

3. Data Sharing

Enable sending usage statistics to JetBrains.

Check for IDE updates (stable releases, early access) and plugin updates. Optionally show "what's new" after an update.

6. Android SDK

Configure the Android SDK.

4. File Colors

Define background colors to distinguish specific project file scopes, and enable their display in editor tabs and project view.

5. Scopes

Define scopes for various IDEA actions such as "Find Usages" or code inspections.

6. Notifications

Enable or disable notifications for certain events and configure their display and logging.

7. Quick Lists

Create custom popup lists (quick lists) with assigned shortcuts (0‑9) for fast access to frequently used actions.

8. Path Variables

Modify IDEA shortcut types, assign shortcuts to specific menus or actions, and reset to defaults if needed.
