Show File in Sidebar

When you startup sublime, you have a bunch of files open. The sidebar however, shows all of the folders collapsed. So everymorning I have to uncollapse the folders. One way to solve this would be to not collapse the folders. Another interesting approach would be to have an option in the right click menu for the file's tab. When you click "Show File in Sidebar" the folders auto uncollapse to show you the file. If the a folder is not in the sidebar for the file, you could add the file's root dir, and uncollapse from there.
