It was easier to copy multiple lessons over

Copying planbooks at the moment is extremely inefficient and not user friendly.There is too much wasted space at the top that otherwise could have shortcut buttons/drop downs instead. I need to be able to take what my mentor teachers have in their planbooks since we co-plan and copy and paste it faster to mine. It would be nice if there at least was a drop down bar at the top to quickly navigate back and forth between my planbook, and my 2 mentor teachers. The ability to copy more than just one day/lesson plan at a time needs to be improved or I will be switching to another application for lesson planning. Preferably, I could hit copy on all the days I want to copy by dragging them to a clipboard/saved area and then dragging/pasting them on mine all at once. I want to be able to go to my mentor teachers page once, copy everything I need, then go to my planbook, and drag/paste where I want them to go. Thank you.
