It looks fine with me except one minor issue above. Thank you!

What issue? Emmacs? That's not an error jaja, my name is Emmanuel, Emma in short so I like to mess calling Emacs Emmacs.

By the way I also modified the text banners face to match the headings and also enabled the init info for it which wasn't enabled.

I tried to use your center-line function but I couldn't understand how it worked so I used the piece of code that was originally on dashboard to center the content as the center-line function calling it before instead of after the centered text.

Sorry! I started a code-review but forgot to submit the comments.

(defvar dashboard-footer-icon (all-the-icons-fileicon ...)

Should consider TTY. This may cause an exception.

Regarding dashboard-center-line, it's a little bit different from yours. It gets the actual width of this line, and inserts some spaces at the beginning. The reimplementation is to calculate with the string width. It's fine unless you don't know the string. In centaur navigator, I create some widget buttons, and I cannot get the string so use current-column to calculate the accurate width.

By the way regarding the dashboard-navigator customization I was thinking about implementing it and came with the idea that the user passes an alist with the icon they want for the button, the text they want in it and the internal/external link that button accesses and that dashboard automatically built the navigator. I don't now how to make a "triple" alist though. Would you help me with an idea?

@ema2159 dashboard-navigator should contain tag (including text and/or icon?), action, help-echo, etc. How about this list?

(defvar dashboard-navigator-alist
  '(("tag1" action1 "help1" face1 ...)
    ("tag2" action2 "help2" face2 ...)))

car, cdr etc. can access the items.

The essential items should be tag and action, so it could be

(defvar dashboard-navigator-alist
  '(("tag1" . action1)
    ("tag2" . action2)))

The widget style of the buttons is push-button or item.

Does that address your issue?

Yes! I'll try that, that'll make Dashboard a really complete and aesthetic package, more than it is right now. From there I don't know what enhancements can be done.

@JesusMtnez I think this PR is good to go!
Edit: Wait a sec, I have a cool idea, I'll put a bunch of messages that will be selected randomly for the footer
Edit 2: Done! You can merge now!

Thank you @ema2159 !! This is a really good job. I'll be busy tomorrow, but it'll try to merge it on Sunday or on Monday.

@JesusMtnez no hay prisa! Do it when you can!

Do you mind moving this last commit to it's own PR?

Of course! It's only two lines tho so is it worth it?
Edit: Done already!

Thank you @ema2159 !!
