Having predefined filters on the list pages will be a very handy feature for end users.

 For example on the All Projects list page, to see all projects in a particular project stage, they always need to follow several clicks to do the traditional filters.

It would be very useful to provide multiple tabs for each stage of the project such as Created, Scheduled, Estimated, In Process, Finished (Except the User defined ones), so that when user clicks on the tabs, they see only the projects in that particular stage.

These are simple enhancements, but can cause significant user experience improvements.
