I love Sublime Text. It's one of my favorite pieces of software. I have it running 100% of the time on every machine I work on. It's where I write all of my personal notes, blog posts, and it's where I wrote both "Game Programming Patterns" and "Crafting Interpreters". At the same time, it's not the tool I use as an IDE. For programming, I use whatever IDE is dominant for the language I'm working in. Over time, that'…
Then I use emacsclient to edit all kinds of files. It loads instantly, handles any reasonable files, can access remote files when needed, and has all the tools I want handy.
OTOH the IDE features do not clutter anything: I have no tabs, no toolbars, no file trees — not until I ask for them.
