You should be able to set/change the access control policy on a bucket when you create it or when you are at the list of buckets.

If a user puts a bunch of files into a "folder" then we should allow deletion of them. S3 has no built-in mechanism to delete all keys that begin with a prefix but we can implement it ourselves

If I drop a directory onto a bucket it should start uploading it, creating a "folder" of the name of the directory, then uploading all contained files into it.

when uploading a large file, it would be helpful to show the percentage done (and possibly an estimate of the remaining time required)

For any s3:/// page it would be nice to have a button to generate a http://... url (or open in new Firefox tab would be even nicer). Good for debugging actual headers, mime type, etc.

A simple mechanism to store multiple sets of AWS keys, and then switch between the respective AWS accounts would be most excellent. Many of us hackers have personal accounts and work/project accounts, and a simpler way to switch between them would be appreciated greatly.

The s3:// plugin is not compatible with Firefox 3.5.

The ability to create a folder.

It could be useful to either use SSL for secure transfer or support encryption before uploading. Would it possible to use symmetric or public key GnuPG encryption? The advantage is that it's available on many platforms.

Have the ability to add Metadata (HTTP Headers) to uploads.

Nice pretty-printed xml view for xml files instead of the weird one currently implemented. Can't easily cut and paste from the listing as is.

As far as I can tell, the program allows to see only 1000 keys max per directory. It would be nice to have an option that will permit downloading all the keys in a directory if so desired.

Amazon added the ability to copy a key, which if you combine with delete, it allows you to rename a key.

if I create a bucket in europe and amazon seems to require redirects for a few minutes, during which time upload sucks since: user get "repost due to redirect" prompt and signature is no longer valid

anyone have a suggestion for a logo?

Firefox is great, the addons for amazon s3 too. But they don't work with international letters like ñ, é, ä, ö, ü in filename or directory name. Has to do with UT-8, I belive.
