VS would be great if it had
1) Batch import of images
2) Change default image import options.
3) More image appearance options.
2) a proper Timeline and tracks (as in other video editors) making it easier to place images and other objects in time.
3) Audio editing including addition of audio to that already in the VS project. The ability to import various audio and place on the timeline.
4) Batch export of VS to video files.
I like the results, but it is really tedious to use as of now.
