Just an idea:
If you were to right-click on a still image file in the media bin, it would be helpful if that very image file would open in the system's default imaging editing software or file extension app association (i.e. Photoshop).
This would not require app-specific programming; just use Windows' file associations.
This, to me, would be a big time-saver; great for fixing issues that show up on an external monitor. (i.e. red-eye)
After the file was edited, it would show up in the project as the edited version, like it already does.
If Vegas can already show the containing folder, this should be an easy tweak to implement.
This would be a very big time saver.
