Tab title starts out with window title, doesn't update.

[Ian Robertson]

It would be nice to have an option that lets title escape sequences set not only the window title, but the title of the currently active tab.

I have my shell set up to have the window title reflect my current directory. When I create a new tab (Ctrl-Shift-T), the new tab takes on the current title of the window, i.e. the directory that I'm in on the currently displayed tab. I often open a new tab so that I can do work in a new directory, and the first thing I will do on opening it is change to that new directory. Unfortunately, while echoing a "\033]0;TITLE HERE\007"' sequence will update the terminator window title, it does not update the tab title, meaning that most of my tabs are labeled not by the current working directory of the shell in that tab, but by whatever the CWD was for the active tab at the time the new tab was created.
