Something very helpful in Resolve and FCP - the option to live preview any media in the source window. As I hover my cursor of a media file in my project panel, it is a MUCH better experience to have it sync/preview to the source monitor instead of only in the project/bin panel. This makes it easier to identify things in footage and quickly mark ins and outs. Two clicks for every file is a massive disadvantage in terms of speed when going through tons of content.
