Admins and Portfolio Managers need to see All of the projects (not just theirs) and they often (almost always) need to see the complete list of projects (not just the first 100).
Provide default overrides so these users don't have to click the buttons every time to get the view of all projects. This both annoying and a waste of time (no value added). This was implemented as an engineering default to limit the record set returned by the server to optimize performance. We're not talking about millions of records from a large scale repository. We're talking about a few hundred (maybe a thousand) records at most. Time to fix this UI constraint.
