Recently I purchased Corel Video Studio 2023. PS26 and CVS 2023 have some similarities but CVS 2023 timeline response and optimization on my workstation is noticeably faster than PS26. IMO Pinnacle Studio would greatly benefit from a proxy creation and management system identical to CVS 2023 

The CVS 2023 proxy creation/managment system offers more user control and works very well while not being overly complicated or too simplistic with no real user options...
