I think it’s more proper and intuitive to use tabs instead of buttons as you change the whole section, no? People will immediately know it will change the content below instead of a button you never know what does.
Even the diskop could use tabs IMO.
just a thought…
Good point actually. Better GUI design in a simple way.
(Another UI improvement could be to differentiate buttons that will pop something up, or lead to another place. Not sure exactly how, though.)
