I remember that time when I couldn't get it why there isn't built-in terminal in the SublimeText and then I found windows managers like `sway` or `awesome` and I started do not care about it.
> PHPStorm's XDebug integration is second to none, it has full MySQL integration, and it's autocomplete and click-through intelligence is incredibly smart.
Support for XDebug exists in all modern editors - Atom, Sublime, NetBeans, etc. etc. If you "waste" some time on customizing your editor auto-completion feature you might will get a really decent one (in aforementioned editors).
I must say PHPStorm had a superior look-for-file (think: Ctrl+P) feature which really gets annoying in other editors if you get used to it.
About the MySQL integration: I was really positively surprised having it in the IDE but I've stopped using it as soon as my colleague told me about the HeidiSQL [0]. For person who was using SQL Management Studio at university, HeidiSQL offered the same feel - fast, lean and simple to use but also it is free and installation in Linux (wine) or macOS does not take much time. It is probably the best application written in Pascal that I know about.
