Missing tab separation and incomplete color line

[MickAmest]

Hello! I noticed that the Default versions (aka Darker) don't have the thin lines that separate the different tabs (title bar looks like a continuous bar). Also, in the teal version, the colour line of the active tab does not fill the entire space, it leaves very small blank spaces (almost unnoticeable) near the edges (left and right). I hope the attached image illustrates this. . I don't know if you are thinking about fixing this.

Best regards!
