You can easily turn any post or page to an event! Set which dates are associated with this event and browse the events through the calendar widget. 
Simply click the event date and then the appropriate post links will be loaded automatically. 
Ody Events does the following: 
1. Creates a custom field for posts or/and pages that helps you inserting dates easily. The feature is available for saved posts, and the data are stored in a new database table. 
2. Creates a new group named “Ody Events” in the admin menu of your WordPress installation. 
3. Creates a sidebar widget. You can drag this widget to any of your sidebars. This widget is a 270 pixels wide calendar, similar to the iphone’s one.

Official Add To Homescreen is a WordPress wrapper for the <a href="http://addtohome.cubiq.org" rel="nofollow ugc">Add To Homescreen</a> javascript plugin. This WordPress plugin guides you through the rather complicated javascript widget configuration.
This is the only WordPress plugin developed by the same author of the javascript widget (hence “official”). If you wish to be always up to date and receive the latest bug fixes, this plugin is probably your best bet.
The plugin opens a message inviting the mobile user to add the application to the home screen. This is currently supported on iOS and Mobile Chrome. While other devices have the ability to bookmark any website to the home screen, only iOS and Mobile Chrome have a straightforward way to do it. Windows Phone support is planned for a future release.
To enhance performance and reduce complexity I’m supporting the latest two OS version for each device only.
<h4>Important! Please read</h4>
Add To Homescreen development started when Apple introduced the <code>apple-mobile-web-app-capable</code> meta tag and <code>standalone</code> mode with it. It was a great news for web developers who had the opportunity to release full screen web applications (and not just websites). The script evolved over time and extended to a more general purpose use case.
It is important to note that there’s no native event we could hook to to know when a user actually added the page to the homescreen. That’s also the reason why this script has become so complicated despite the apparent simple task it has to accomplish.
Unless you explicitly developed your application to be <code>mobile-web-app-capable</code>, this script can’t do miracles and all the alternative solutions have to be considered hacks.
The Basic configuration gives you four presets, the only 100% fail-safe solution is to select the Anonymous option. This disables user tracking but it doesn’t interfere with other plugins you may have.
Considering the complexity of the script, before filing a negative feedback, please drop a support request or a bug report. It’s the only way for me to enhance this software. Thanks!
