Google Spell Check, WordCount, and Wrap Plus for docs. LLVM for IR highlighting, Rust for Rust highlighting. I've tried racer in the past but it just doesn't scale with the current compiler architecture. I'm hoping the ongoing refactoring work will get us a great incremental/parallel/continuous compilation system for autocomplete/red-squigglies. My two biggest pains are: "trivial" errors (syntax, typos, etc) which I ideally would just see as red squigglies as I go (not a compile-fail loop); and the absolute lack of any kind of incremental compilation (which paired with the community's over-use of generics is super painful for codegen time).
