Thes 3 issues are all related to an imcomplete implementation of floating IP's. And not all people know about this - so I would not immediately expect high votes. Great ideas do not always come in numbers..
I have had contact with several admin/support users from DO that confirmd that it is crazy that the below items have not been implemented.
Please may I ask for your help together with the other sysadmins out there. Please please make this happen.
