I propose a new feature to webgui that will allow users to update the rank of all the assets displayed in the asset manager.
We all love the new asset manager and how it uses the YUI DataTable. The DataTable allows us to sort the assets by rank, title, menutitle, type, date, revision, and so on... Now let's use that to reassign new rankings to all of the assets that we just sorted using the DataTable.
When you have your assets sorted the way you want, for example by menuTitle, you can click the 'Update Rankings' button that will reassign new rankings based on the order that the DataTable sorted your assets.
