Whenever I am working on a project that has hi-res images or alot of clips, I usually have selected Media Bins(so as not to show any thumbnails) to speed up while working on the timeline. Everytime I do a ctrl-z or edit undo it takes forever to reload the project and resets the media pool back to all media. Is there a way so it doesn't go back to all media and stay on the bin you currently have selected so the project reloads quicker?
