\section{Personal notes with multiple counters}

Hey there ! Here is a quick gist to create a note inside a texte with one or multiple counter

Here is a first bit of text I want to refer to with a counter (mycounter) \note{mycounter}{test1}.

And here's is a second one I want to refer with it (mycounter2) \note{mycounter}{test2}

Now imagine I want to use another counter (because I'm in another part of my doc for example) and refer to it \note{mycounter2}{tut1}

And again use this counter in this bit of text \note{mycounter2}{tut2}

---

\ref{note:mycounter:test1}. Here is a reference to explain the ref test1 of mycounter

\ref{note:mycounter:test2}. Here is a reference to explain the ref test2 of mycounter

\ref{note:mycounter2:tut1}. Here is a reference to explain the ref tut1 of mycounter2

\ref{note:mycounter2:tut2}. Here is a reference to explain the ref tut2 of mycounter2
