Isolated module

Hi,
The application is not really designed in a way to be extended, but it is possible in some ways to extend functionalities.

To add new funtionalities : no issue, you just create new classes, add needed items in the Menu table, add some icons and css (see porjectorIcon.css). This will not generate conflicts with furtur versions (unless future version create new classes with same name).

Next, if you want to update existing class : the best is to overide with a new class. For instance, if you want to extend "Activity", create "MyActivity" that extends Activity, change name in the Menu talbe so that you'll reach your object, and you're in.

Worst, if you need to update some common functionality (for instance in projector.php) : you must save your changes and merge them on each new version.

Finaly, you'd probably like to add new captions : you must update lang.xls (search for translatable in the manual) => just tag your changes in the version column and save them : you'll have to paste these changes after each new version deployment.

It's a bit short for a long subject, but hope t's enought for you to work.
Regards.
