May be it exists and I missed it, but…
Each time I try to open a project from an already opened one I use the Menu, and Cubase opens the last project folder letting me select a project file, but I have several project folders and each time have to change to a new folder.
But Cubase knows for recent projects I worked on … it could be so nice to be able to see a list of recent projects just as on the initial startup.
That’s at the bottom of the menu
