Support reading function parameter lists in IntelliJ

I’m not sure whether I should post this here or in an IntelliJ forum.

I am programming in Kotlin for 2 weeks now, and it is really great. But there is one thing that I am still not used to, which is reading a function’s parameter list. There is too much punctuation.

In Java there is only one punctuation type in parameter lists, which makes them very easy too read. In Kotlin parameter lists, there are 2 punctuation types and there is at least twice as much punctuation in Kotlin function parameters compared to Java methods arguments.

I tried improving the readability of Kotlin parameter lists by tweaking the appearance of parameters in Intellij’s editor color scheme. For example I can make parameter names appear in bold. Indeed this helps a lot. Unfortunately changing the appearance of parameters in IntelliJ will not only change its appearance in the parameter list, it will also change the appearance of every occurrence of thr parameter within the functions code, which is annoying.

Is there a way to change the appearance of a parameter within the parameter list only?
