PeopleSoft Classic Plus has replaced the traditional PeopleSoft Classic User Interface as the standard user interface for PeopleSoft applications. PeopleSoft Fluid, introduced in PeopleTools 8.54, has co-existed with the traditional classic user interface in all PeopleSoft applications and will continue to do so. The introduction of Classic Plus is a step toward unifying the look of all pages, the “classic plus” feature allows reworked classic components to be displayed in a Fluid-like manner. Classic Plus basically serves to standardize the look and feel of Classic and Fluid PeopleSoft pages from a styling point of view.
