Very simple. Up and running very quickly. No bells and whistles and configuation is very limited. Some nice wishlist features would be customizing the format of date and time. M:D:Y vs D:M:Y and 24 hour vs 12 hour time standards. Also being able to adjust the calendar to fit your template screen resolution would be good. I have a template at 800 x 600 and Sunday wraps around to a second row with the current beta version of the component.
Other than that...a very good simple, easy to use, out of the box calendar without any apparent bugs. I LOVE the css and how clean and unencumbered it is (ExtCalendar, take note). Great start!
Owner's reply:
The entire layout is completely stylable through css, so it shouldn't be hard to adjust the calendar width in the css as well.
As for date format, you can define what output you would like in the Easy Calendar language file:
define('EC_DATE_FORMAT', '%d-%m-%Y');
define('EC_TIME_FORMAT', '%H:%M');
You can use anything that's mentioned here: http://www.php.net/strftime
