Feature: Color a tab

[ik5]

Hi,

I have a feature request:

Choose a color for a tab button for easier identify what is each tab. It's not instead of title etc, but for easier and faster identification when there is a need for it.

Without choosing a color, it will be the same color as today, and when choosing, I can also choose to remove it back again.

The tab color button that I'm talking about is this (If it has another name ;-) ) :

Thank you

I'd love to have the same feature.

For example I am connecting to multiple remote hosts at the same time. One tab is shell in a local docker container, one tab belongs to SSH session on a remote host and so on. I'd love to be able to change the colour of the title to red if I am connected to a production system for example.

That would help me to differentiate where I am running commands.
