Activate the clip placed in timeline, not another

When an image is dragged from an outside folder (i.e., Images) onto the timeline, have that be the active clip, instead of another, so when features are applied, we are not inadvertantly adjusting a clip that is not showing in the Program window that is not to be modified--obviously--because if I had wanted to edit its features, I would have been viewing it in the Program window!) Thanks!
