Re: Tab bar

[Richard Stallman]

    I'm not wedded to the idea of having a separate window for each tabbar,
    it's just an idea for how to create a more flexible tabbar entirely
    in Elisp.

This must be implemented in C, so that we can adjust its appearance to
make it look right.  Given that, I think other half-baked
implementations are not very useful effort.  What we need is for
someone to implement tabs in C, using toolkit widgets for
toolkits that provide them.
