I would like some changes made
1. I would like the zoom focus to match the point where the mouse is when zoomed
2. I would like the save and load functions to save the current state of all of the data and apps in use
3. I would like references to the apps to be optionally stored with their associated file types so the app is loaded when a matching file type is dropped
4. I would like to be able to drop PaperScape configurations into PaperScape to add multiple apps
5. I would like to be able to create pages that run PaperScape with app configrations loaded in their page.js files so instances for specific tasks can be created
6. I would like file and app drops to work when the left menu is visibile, currently it only works when the left menu is closed

I would like paperscape to offer some more services to apps
5. I would like it to offer a generic undo redo service
6. I would like it to offer keyboard mappings to functions
7. I would like a new background layer under the view layer

Please create a sub page, ProjectPlan, with a view of these changes as a plan that we can reference and tick of as completed
