I'd say, every professional developer used @Xdebug in one or the other way in their work. But debugging Neos or Flow applications can be challenging, since Flow generates proxy classes in a different directory than the original class. @derickr kindly created a proof of concept for supporting our case in Xdebug. Now we are raising funds to make it really happen, and we almost reached our goal: https://www.flownative.com/en/blog/flow-support-for-xdebug.html
