Redo Shortcut - Ctrl + Y
Sometimes I use the undo shortcut once too many. Please allow Ctrl + Y for a redo. Even if there's only one possible redo, I'd take it.
You can redo by pressing Shift+Cmd+Z (Mac) or Shift+Ctrl+X (Win).

As a new user I too was expecting Ctrl+Y; please allow custom mapping of shortcuts like PS does.
You can redo things with the shotcut ctrl + shift + Z
