Save just the workspace

Saving just the current open files in to a single double-clickable file would be essential for my workflow. Current Sublime Projects are an overkill for this purpose. My projects don't usually consist of files being in the same path, so I don't want the extra hassle to define these useless folders in my projects. Also I need to save my workspaces to the desktop for quick access, and the current 2 file project model clutters my desktop quickly.
