TSLint Warnings instead of Errors in Webstorm

That TSLint rules in Webstorm are displayed as error messages is something that drives me nuts. Today I discovered that one can change that behaviour in Webstorm:

• Preferences -> Editor -> Inspections
• Select linter (TypeScript->TSLint, or just use the search box with tslint
• Change Severity to a desired level like Warning or Weak Warning
