Hi M.L., Our projects also number in the thousands. We try our best to design a view and access framework, using wildcards and groups, to optimise the experience for our end-users - ideally, using custom dashboards in the place of the project tab, they only see the projects they work on or need access to (between 25 - 100 projects). However, as a system administrator, the lag on lengthy lists, organisation-wide report building etc can be a pain-point. Our Workfront advisors are currently looking into system speed performance and confident a resolution is on the way. Also very excited about the New Workfront Experience which may remove the need for list views in the future. Best regards, Christian Barnes iProspect UK
