The coloured TABS for grouping is awesome, can we have the colours synced to the original TABS across the top?

This is basically the best tab addon for firefox currently around so great job! I was wondering if it would be possible to add in synchronized colours that you pick on the left side for your groups if they could be synced / clevery incorporated to where the original tabs are horizontally across the top? That would be sweet!

Keep up the awesome work!
