Well ... turbo can be achieved by the LW Basic version but only a few people achieve it. The Pro version achieves it by default.

All versions have a Resume function in the Library window. The LW 4.16 version also has it on the first window at the bottom as did many of the older versions. Not sure about the latest version.

Right-click and choose Resume, not sure. You have a right-click Find Sources option. If this does not work, then the option becomes a right-click Resume option next time you right click that same file. It was always a Find Sources/Resume option on first window.
