Command \marginnote already defined

Question

I have included the package typed-checklist in my journal document which uses the documentclass tufte-book. Now I get the error "Command \marginnote already defined."

I use this command to note the date as shown in this post: Using LaTeX to keep a diary

Apperently the typed-checklist package uses \marginnote to display deadlines in the list layout.

We use the marginnote package to display deadlines in the list layout. https://ctan.joethei.xyz/macros/latex/contrib/typed-checklist/typed-checklist.pdf Page 32

Is there a way to be able to use tufte-book and still make use of this package?

Answer 1

Solved it by making use of the savesym Package as described here: https://texfaq.org/FAQ-alreadydef

\usepackage{savesym}
\savesymbol{marginnote}
\usepackage{typed-checklist}
\restoresymbol{TXF}{marginnote}

Did the trick.
