There was the live site editing option in portal engine - when the site was also served by the Kentico app. However, in Kentico 13 the web site is served by your front end app which means that there could be a custom routing in place or, the URL in the browser may not reflect the content tree path - this means that there is no built-in feature for this in Kentico 13. And since it depends on how the front end app is designed, there is also no universal trick for this. The only recommendation is to keep the content tree well structured and organized.
