How can I hide the validation/marker error bar on the right in IntelliJ Idea 10?

Question

The right side validation bar that shows yellow markers for warnings and red markers for errors.

Answer 1

There is no way to hide it as it's combined with the scrollbar.

However, you can adjust the severity settings for errors and warnings so that they are not displayed in the stripe as marks in Settings | Editor | Colors & Fonts | General:

• Error
• Warning
• Weak Warning

Disable Error Stripe Mark checkbox for the elements above.
