IntelliJ IDEA Global Configuration Tips and Tricks

Welcome to 顶尖架构技术栈 ! I am Xiao Er Ge.

Preface

Recently I noticed my IDEA version was a bit outdated, so I decided to perform a major upgrade.

To keep the environment clean and tidy, I chose to uninstall and reinstall IDEA, which also removed previous configurations and plugins, requiring a fresh setup. Below are several handy global configuration tips.

IDEA Global Configuration Tips

1. Optimize Import Settings

Path: Settings → Editor → Auto Import

2. Disable Single‑Line Tab Display

Set the number of open files displayed.

The result looks like this:

Opened files are clearly visible, making navigation convenient.

3. Move Double‑Slash Comments to the Top of Code

Before‑after comparison:

This improves layout aesthetics.

4. Disable Strict Case‑Sensitive Matching

This makes code completion more convenient.

5. Auto‑Generate Author and Creation Time When Creating Files

You can also customize file templates.

That’s all for today’s tips.
