Add (Year) to footnotes in BibLaTeX-authortitle

Question

I am really happy with the authortitle-style provided by BibLatex. I am using it to cite in footnotes (with ibid enabled). The first mentions of a citation look something like this:

1 Medina, Cybernetic Revolutionaries, S. 127.

Yet I would like to give my reader a direct glimpse at the year in which to entry has been written.

1 Medina, Cybernetic Revolutionaries (2011), S. 127.

It does not need to reappear when in "ibid."-mentions, it can stay like "vgl. ebd., S. 128". Nothing else has to change.

Is there a simple way to do it, or do you have a style in mind that enables this (or similar) by default?

If it is to complicated to implement because it needs different commands for every entry type, I would also be okay with the following general rule, where the Year appears in brackets directly after the author:

1 Medina (2011), Cybernetic Revolutionaries, S. 127.

Thank you so much!

You can apply the following redefinition of the cite bibmacro from authortitle-ibid.cbx (ll. 18-26). The idea is to add a new bibmacro that prints the date.

\documentclass[ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber, style=authortitle-ibid]{biblatex}

\newbibmacro*{cite:date}{%
  \DeclareFieldFormat{date}{\mkbibparens{##1}}%
  \printdate
}

\renewbibmacro*{cite}{%
  \global\boolfalse{cbx:loccit}%
  \iffieldundef{shorthand}
    {\ifthenelse{\ifciteibid\AND\NOT\iffirstonpage}
       {\usebibmacro{cite:ibid}}
       {\printnames{labelname}%
        \setunit*{\printdelim{nametitledelim}}%
        \usebibmacro{cite:title}%
        \setunit*{\addspace}%
        \usebibmacro{cite:date}}}%
    {\usebibmacro{cite:shorthand}}}
