Maybe I'm doing something wrong, I got java/maven plugins but there is no XML highlighting. Java does have highlighting but that's it... OH, and and I installed it this time and I noticed "downloading json-language-server"... (it was there before probably but didn't notice)... like WTF - didn't even ask if I want to... utterly rubbish experience.
For a simple text editor I prefer BBedit on mac, which is native and blazing fast. And for something slightly more complex I usually end up with `code <file>` to quickly edit it...
