Last week I started to use PhpStorm after using Vim for >10 years. Magento 2 contains 1000s of files split over 1000s of directories. And every file you want to use has to be specified in full, and often more than once. Too much typing. PhpStorm helps with that.
I started with using "refs" in the microsub items. When it's available in the original feed, Ekster will try to add it to the refs array.
