I'm testing OpenERP 7 Project and i do not understand how can i use the Gantt view (Project/Task > gantt) :

This gantt show all tasks (of project task or selection) in the single view without scaling options (i do not find anything). So with several tasks and/or pojects the gantt became wide (very wide) : you can of course scroll in the navigator but you do not see the label, so you don't know what you see...

I also find to way to print the gantt : it was an important document for meeting...

OpenERP has many nice option and data for project management but Gantt view seems to be not useful in real world, but i probably miss something, i'm a novice.
