More transitions?

Can you add transitions and enable the Kens Burns effect for videos too? I love this app for editing but the transitions are weak and the kens burns effect for videos would be great. EDIT: This app is awful. I cant edit on this anymore because when I try to edit a clip it doesnt edit it. Literally. I hate it. Waste of 6 dollars.
