Can you, please, make connection tabs more distinct, like more of contrast color? Now the ACTIVE tab = HOVER tab, which makes it impossible to differentiate the active one from the one you have mouse over, so you need to move mouse away to notice the tiny difference in tabs (the small tiny arrow) to recognize active tab.
I know it is not a big deal, but why not make it more user friendly? Why not optimize user experience for quick and easy work? I sugges you make active tab colored with totally contrrast color, so it would stand out.
