Perhaps you should check the Preferences setting for the Titlebar enabled/disabled setting. There is a lot of info about configuring the spaces in the Usage page (link to the Usage page from the Preferences page).

I think it might be possible to set font and perhaps color. You might think the outline is untidy, but I found it made it easier to see because it sets it off, but I could also make it optional. I've actually given this some thought, probably using the sidebar for the dialog, so one can easily see the changes. However, unless a lot of people start using this, it's hardly worth the effort.

I primarily made this because I personally wanted it, couldn't find one that worked well, and thought others might find it useful. It's definitely more about function than looks.

I'm not sure that an avatar (like Chrome?) is feasible. I'm definitely not interested in such eyecandy. :P
