Very promising plugin but after reviewing the plugin I have some remarks (R), feature requests (F), and some bugs (B) to report.
Features:
1 - Ship a widget with it. See my Agenda Widget.
2 - Show today's and all day event's until their end time.
3 - Remove time notification when it's a all day event.
4 - Change $title_tag into to the $before and $after model for more template flexibility.
5 - Localization by translation domain. Change __('text') into __('text', 'agenda'). Have also used that in the plugin I have created.
6 - Ship a .pot with it for translators. I will translate into Dutch when available.
Bugs:
1 - When repeating on a daily basis the start time changes (looks like the function add (for example) 24 hours to the end time instead of the start time). )
2 - Visual editor isn't working.
3 - Time droplists are out of sync with the input boxes (further to the right).
4 - When using agenda_compromissos() the 'a href' tag isn't populated.
5 - Add 'no events' message when there are no events to show, I'm now getting an error message.
6 - Styling doesn't fit in the (smaller) crazyhorse design of 2.7 and perhaps it's an idea to stick with the WP colors for the background.
Remarks:
The 'Event' page should not be registered as a menu item when you use 2.7 as the structure of the menu's has changed. The Add New link on the Events page will follow the style WP is using on the Posts and Pages pages.
Questions:
1 - How can you get the location and date(s)/time(s) visible in the post?
BTW - At the moment I'm using WP 2.7 r8736 and Firefox 3.0.1.
