I’m glad I can help. The deadline on my current project is approaching rapidly, and I’ve been working for 21 hours straight now. Only with the occasional breaks where I’m taking a look on this forum or the ones of a more natural character. Looking at other peoples problems is a great way to get renewed focus – it is like meditation for me ;-) The time is 9am here in Northern Europe, so I take all I can get ;-) ;-)
I got another idea while looking over your design a second time. I’m thinking; try making the orange border on top of your profile-text-box go around the borders of the active tab (the greyed out “Profile” in this case).
I think that would make it look extra polished and make it even more obvious that it is the active one.
