code style: make warnings more prevalent (e.g. put on top & make red)

Maybe i'm missing something, but i can't make the "indent size" setting in Options->Editor->Behavior to have any effect on text auto-indentation as i'm typing. Whatever value i set, Creator is still using a 4-space indentation.

I'm attaching a screenshot with my settings, just in case the other settings might be relevant (i've set auto-indent at 3 but it has no effect, it's always using 4 spaces)
