I like this plugin - it is quite useful. However, I had to hack my way to do something that I figure should probably be a feature.
Currently the plugin scans the account that you enter for its buckets, and lets you choose one of those for the backups to be placed into. This is fine, except I wanted to place those backups in a bucket that wasn't on my account, but I had permission to.
I'm thinking the dropdown for bucket selection should perhaps also have a textbox for entering ANY bucket name instead. (My hack was to use the Firefox web developer plugin to change the select drop downs to textboxes, which allowed me to enter whatever bucket name I wanted).
Enabling this functionality may also solve another issue that I can't seem to hack around. I would like to be able to save to a write-only bucket, but that also seems to be an issue with this current plugin.
Just a couple suggestions. I do love the plugin though.
