Hi,
I'm using the latest svn version of Projectpier.
And I'm having an issue with the rendering of the calendar milestones:

- 1. There was a shift between the day number and the name of this day (5th of september was shown as monday instead of sunday for example). I did change calendar.php according to this post:
It works good, but now monday is shown in darker blue... so as a weekend day.
Could find the painting options or definition of weekdays/weekend days...
Can anyone point this out for me?

-2. I'd like to highlight the current day in the calendar in red or something alike, in order to locate it better in the calendar view.
Same thing: where is the 'painting' of the calendar's cells performed?

Thanks
