After upgrading to version 3.0.2 the SSH Terminal File Transfer feature is missing in the SSH toolbar.
The option is enable in Global Settings and the plugin menu was visible before the upgrade.
1. Go to Global Settings and disable the "SSH Terminal File transfer" option.
2. Try to connect through ssh to a target
3. Renable the "SSH Terminal File transfer" option again.
4. Try to connect to a target again
That sequence solved the problem, and now the plugin menu is visible while connecting to all servers.
