Scrolling in the options window
Change the behaviour in the options window in a way that the scrolling will be based on mouse pointer position. For example now, when you are in options->contacts->ignore you're scrolling that part (ignore list) even if your mouse pointer is in the left part (long column with all settings). And maybe also discuss the default behaviour right after opening the options window: (sometimes unintentional) scrolling changes the setting in upper right field (modules) which consequently changes the options window as a whole. I think it's better/more intuitive to scroll left panel by default.
