When a user click on Data ---> activities
he presenrd with a list of all activities because filter fields are empty
all activities are listed based on Activity Id
Now, is it possible to a add sort feature like this
Sort by: Teachers
________Students
________Duration
________Subject
________ Act Id
So for example, if you select teachers, all activities will be listed alphapetically in a ascendent order
I added it in the TODO, it is a nice suggestion, but too complicated for the moment.
