Besides Firefox, Sublime Text is the application I use the most in my day-to-day professional life. It is faster and easier to configure than any other code editor I've used in the past. I would say it's one of the few pieces of software I've encountered that is a joy to use.
If you also use ST regularly and can afford it, I highly encourage you to support development and buy a license right now.
I purchased the licence years ago and used it almost exclusively until I got familiarized with vim. It's way more powerful and can do anything that sublime can. Plus more.
The only downside is the learning curve, but you only go through it once.
