I think the "explorer" and "automated backup" are two different products and they should not be merged. If you think it should be added to the current product
The debate between those who prefer multi-purpose software vs. those who prefer specialized tools will never be resolved. Here's my thoughts (CAUTION - opinion of ONE):
To me, S3 is just an address on the 'net that stores my backup files in one bucket, and my website files in another bucket. Ideally, one program that uploads/downloads to and from either bucket is all I need, and would be convenient. I don't see the point of using one app. to work with one bucket, and a separate app. for my other bucket.
Add in scheduled background backup, and you have it all in one app.
