Improve appearance of tabbar and support link

In this tab-bar, the support link stands out a bit:

Can we:

• Use 16px font size for tabs and support link
• Remove the icon
• Text-align it so it lines up with the text inside the tabs
• Use the same font size as the text in the tabs, and underline it

Can you clarify this instruction:

• Text-align it so it lines up with the text inside the tabs
• Use the same font size as the text in the tabs, and underline it

Are you expecting something like this?

Are you expected something like this?

Yes, exactly that, except you can keep the Support link blueberry in color.

This becomes the only underlined link that's not part of the content. Do we plan to underline all the links?

[jasmussen]

I think so, yes, and I believe that was one of the suggestions from a separate issue.
