It would be great to be able to configure this as an option. The biggest problem I have with the single-click preview is that if you have multiple documents open in tabs, then go to right-click on a file in the Side Bar, the focused tab is lost so you have to then locate the document you were previously working on again. It's not a problem with only 2-3 files open, but when you're jumping between 7+ it's annoying to lose that tab focus constantly when you're just trying to copy a file name or directory structure.
