- Ask Google first if it's not very editor-related. (e.g. How to install Clang Format? What does this compilation error mean?)
- Search in the Issues and make sure your bug report/feature request is not duplicated.
- Please follow the issue template and provide detailed information, it will help us to give you better feedback.
- If it's a feature request or bug report rather than a question, please open an issue instead of asking on Telegram or Slack so that it can be tracked easier.

- Now you can use whole-application dark theme on KDE, macOS and Windows 10. You need to set the system theme to dark theme, then CP Editor will use dark theme, too. However, on Windows 10, if you use the dark theme, you may need to restart the application after changing the theme of the code editor.

- How to enable error linting in the code editor?
