@danielleget15 Feature Request posts should go into https://community.fxhome.com/categories/hitfilm-feature-requests.
Since you have several items listed, some may already have a post associated with them in that category. Find them and give them an "Up" vote.
If not, you can create a new post for each completely separate item on your wish list (or keep them together if they are very similar) and then the rest of us can up vote Up your posts in Feature Requests.
I will attempt to answer your first question (if I understand it correctly). You can zoom in and out on the Edit timeline using the Control key and your scroll mouse wheel.
