Find files in dired in tab-bar-mode

I have been experimenting with `tab-bar-mode` which I have found very
useful for arranging my workspaces. I frequently open a directory in
dired and like to work from that. I can open files in `tab-bar mode`
using `C-x t C-f` but I would like simply to be able to simply `<ret>`
on a file in `dired` and have it *optionally* open that file in a tab.
I say *optionally* because I would not like to do this with all my
files, but only when I choose to create a workspace of tabs.

This function will open the file in a new tab when given the prefix
argument (`C-u`), but behave normally otherwise:

     (defun dired-find-file-maybe-other-tab (&optional prefix)
      "Open the file at point, in another tab if given PREFIX."
      (interactive "P")
      (if prefix
          (find-file-other-tab (dired-get-file-for-visit))
        (dired-find-file)))

You can bind it to `<ret>` in `dired-mode` like this:

    (define-key dired-mode-map (kbd "RET") #'dired-find-file-maybe-
other-tab)

I will test it in the morning when at my PC. Many thanks for replying.

Use the C-x t t prefix when you want to open a file in another tab.
