Some of it's new features:
-Ajax. Through the use of Ajax you can now create, edit and delete accounts without having to reload the entire page. There are 2 clear advantages to this: 1; Server load. You are only performing 1 or 2 DB calls to perform the action instead of all the DB calls requiered for a standard page reload. 2; Time/User interaction. Since it's only doing 1 or 2 DB calls things go a "LOT" quicker.
2- Scriptaculous. This is a set of javascript routines and effects to give users a more "rich" internet experience.
3- Multiple accounts per user. Now each of your users can setup several webmail accounts. You also select 1 account to be the default when you first login.
4- Iloha mail 0.9. Tropical mail now uses the latest version of iloha mail. This new version uses a native Ajax engine to speed up it's operation. It also has some new features such as RSS and public contacts. Please bear in mind that some of them aren't yet fully operational.
To be implemented:
Cpanel routines for automatic account creation, edit and deleting.
