I am a bit different because I'm not a novice, but I use a lot of languages (I'm an independant consultant) and syntax higlighting is very important for me to switch from one language to another, or even jump into a new one. My ideal situation is to have a language that Jetbrains tools understand, because I also learn things by just having the IDE extracting a variable or a function, I can understand some weird variable or type things by the way they typed the extraction.
