LINUX program combining for TO DO list + Gantt Diagram + Agenda ?
 

Hello,

It would be great if we had a similar program for Linux that combines for TO DO list + Gantt Diagram + Agenda ?

we have that but it doesnt show to do list nor has any Agenda capability

Thre is qtodo and gtodo but there is no agenda (like in kde kmail/kontact suite or outlook agenda) nor Gantt bar diagrams ways to make with sub categories

Best regards
