S3 service window missing tooltips on important fields
There is no tooltip on the IP Address dropdown field, yet the choices include 0.0.0.0. Does this mean "provide the service on all addresses or interfaces"?
There is no tooltip on the Port, which assumes the reader knows what a port is. How about "TCP port on which to provide the service (default 9000)"?
The Secret Key field just says "S3 password", but this does not make it clear whether the user is setting a password that other systems will use to connect to this system (probably), or just entering a password that will be used to connect to other systems.
The Disks field just says "S3 filesystem disk(s)". First, there are people still in jail since the 1950s for pluralizing with a (s), please don't do that. Second, what does this mean? Is it supposed to be a list of devices or directories or what? How are multiple entries selected? The tooltip needs details on this. Space is not a premium, so let's splurge and explain what this means, maybe even give an example.
Mode says "This doesn't do anything yet"... so maybe we can hide this field.
Enable Browser says "This will enable the web UI for the S3 service." Let's make that more clear: "Enable the web user interface for the S3 service."
