I use the calendar in month view and sometime find myself scanning for todays date. In this view with many events being displayed the simple ring round the date doesn't really jump out.
My old google calendar (which I'm trying to get away from) has today inverted which I find much more visible. Looking at it now, it is a solid blue circle with white text, I personally find it very easy to find.
I'd just like today highlighted a little more strongly than it is now please.
