Improvements to Tab Group UI

The tab group UI looks very poor in Brave compared to Chrome (possibly due to the smaller height of the tab bar) - see below.

Granted this is just my opinion, but I think the following tweaks should be made in order for this to look better.

  • More space between tab label and the first tab
  • Reduce height of the colour outline
  • Add some space between the outline and the tab
  • Rounding the label and adding padding to either side will make this look nicer
