Plug application task

A proposition to use Task Manager Application as a task tool in the Project Management Application.  See my comments on the code on where there may be problems.
These empty lines allow the livetable to be displayed below the panel to create tasks.  This is a buggy fix but for now it works.  Any idea on how to make it better?  Because I don't know why the table is displayed on top of this panel (without these empty lines).
