For me syntax highlight is one of most important programing improvements, almost as important as IntelliSense. Where IntelliSense is major for writing and syntax highlight is major for reading code.
Here is an example of what I’m talking about:
Code might be very complex and every facilitation are needed. Eg. Someone could write priceChange(price); you see braces you could think that it is a method, even if you suspect it could be some event you could not be sure unless you could distinguish them by color.
Other example you see some variable how to recognize is it a field, property, local variable without searching into code? Yes by it’s color.
