When working in a project with multiple files, it would be nice to be able to change the visibility of individual objects. Similar to the way layer visibility works in a program like photoshop.
In the file list, you could simply add an 'eye' button next to the trash can that would make the selected files visible or invisible. It would be very useful in being able to focus in on one object at a time without being obstructed by objects and their supports that you are not actively working on.
