It would be good if you could change the timeline in the Gantt chart view so that the timeline can be condensed, allowing the view of a project to be tailored. At present it seems to display 5-6 weeks of activities and this makes it hard to see multiple project activities that span longer timescales.
I notice on the All Projects view this now exists and if you view as a Gantt chart view of all of your projects you are able to change the view periods.
