views display information focused around individual SNPs (data not shown). Information presented in a single view in previous versions of Ensembl is now presented as separate smaller views in the new design. The relationship between these new views is clearly shown by the left hand hierarchical menus which is context specific for each class. Each view within a class has a common header panel, summarizing the location or object. Clear and easy navigation between views is provided through the left hand menu and the left and right buttons below the header panel. Since only a specific chunk of information in shown in each view, this makes pages easier to read as well as improving the responsiveness of the servers. Configuration controls have been considerably improved and now take the form of a context specific pop-up panel for most views, e.g. allowing tracks to be enabled and disabled in genome sequence based display elements. The same panel contains controls to allow external data to be uploaded into Ensembl, or for external data sources to be federated (DAS).
