CTRL-T adds seleted item to the queue. What about the default behavior of download NOW?

The new behavior might be useful if you only have one connection open, but what if you have multiple connections open and you want to download something immediately?

Also, I've always been confused by how many settings dialog screens SmartFTP maintains... Also, 3.0 installation did not port previous settings from 2.5 which is also not very well behaved for an upgrade.

Ctrl+T works for me. The items are added to the queue and downloaded immediately.

Also SmartFTP imports all settings from version 2.5.
