[Feature request] Eye-catching super user (root) indicator.

[heit0r]

Is your feature request related to a problem? Please describe

I feel like tide could have a more colorful super user (root) indicator. I have a lot of terminal instances and sometimes it gets difficult to differ where are the root instances. I love fish and tide over any other terminal emulator I have used so far.

Describe the solution you'd like

The prompt configuration at tide configure could have an extra option on what colors should appear when one log in as super user. This option could have something like a red background with white fonts at the root indicator or a complete color change on the whole prompt.
