## Color Mode & Query Font Size

### ![](https://1143774439-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F1ooXfQ2qWGFRh6lihybt%2Fuploads%2Fgit-blob-35dc2843a5ae9450599c963806bcc77092e8a603%2FButton_config.png?alt=media)

OMrun supports both dark mode (default) and light mode for the user interface. Additionally, you can adjust the font size of the query editor. You are also able to select a default reporting application for exporting results to a Microsoft or an OpenSource product.

### Steps to Customize Look & Feel

1. Open the configuration window.
2. Navigate to the `User Settings` tab.
3. Select your preferred color mode (via dropdown: `Dark Mode` or `Light Mode` ).
4. Choose a query font size (via dropdown: 9–18).

### Customize Default Reporting Application

By default, OMrun exports results using the application set as the Windows default for `.xlsx` files (Default option in the dropdown). Alternatively, you can change this setting to `Microsoft Excel`, `OpenOffice Calc` or `LibreOffice Calc` regardless of the default application set by Windows (and of course, these apps must be installed locally beforehand).

### Warning :warning:

> Changing Color Mode or Query Font Size requires restarting the application. OMrun automatically saves your work, so no data loss should occur. However, we recommend completing your work and closing all open tabs before changing these settings to avoid any potential issues.
