Thanks.

Is the argument 'current-p' really necessary?
It's easy to check if the argument 'tab' is current
with (eq (car tab) 'current-tab).

The argument 'current-p' was required for group-related functions since
it's harder to get the current group.  But for non-group it's simpler.

> +  (concat (alist-get 'name tab)
> +          (if current-p " (current tab)"
> +            " (click to visit tab)")))

This suffix would be nice only for demonstration purposes,
but in real use this extra text only adds visual clutter.
