 The servers are listed / edited  in a grid. 

 <ul>
  <li>To edit a cell, double click on it. After a cell is changed it
      will flags one of its corner to red to indicated that it has been
      changed. To commit these changes back to Tvheadend press the 
      'Save changes' button. In order to change a Checkbox cell you only
      have to click once in it.

  <li>To add a new entry, press the 'Add entry' button. The new (empty) entry
      will be created on the server but will not be in its enabled state.
      You can now change all the cells to the desired values, check the
      'enable' box and then press 'Save changes' to activate the new entry.

  <li>To delete one or more entries, select the lines (by clicking once on 
      them), and press the 'Delete selected' button. A pop up
      will ask you to confirm your request.
