Even if I have ripple off, pasting a clip still moves everything else in the track.
This makes it extremely difficult to edit videos, and I am considering downgrading to the previous version until this gets fixed.
Pasting will do that. If you want to lay a clip without moving other clips then overwrite the clip to the timeline don’t paste it. The Overwrite button is of an arrow pointing down in the toolbar menu and the shortcut key is B.
