# Is it possible to make todonotes package use margin outside pagetrim for draft notes?

In the memoir manual there is a snippet for making draft notes that uses the entire paper when printing drafts on pages bigger than the trimmed papers. Is it possible to get the more fancy notes of the todonotes package to use that margin space as well? I think the readability of white on magenta as in this example is much higher and I really like to have the line provided by the todonotes package as well.

If the todonotes package can't do it, is there some other alternative in order to get my dream-behavior? :)

EDIT:

• Added more lipsum to make it two pages
• Added \sidepar to show that margin notes that are not draft notes should be on the trimmed page

You can use the textwidth option of the todonotes package to specify the size of the margin note. Usually would just increase the size of marginpars, after your page set-up for memoir, but if you don't want to change that dimension, it is possible to rewrite some of the internals from the todo package, hiding the width of the todo notes:

• Neat, but it only works on the first page. On the next page the margin is on the left side and increasing the textwidth places the todo note on top of the other text. Updated the example code to use two pages. – jonalv Mar 13 '15 at 14:36
• Hm that seems scary, isn't that thing used for other stuff when setting the page which will be problems for the not draft notes'' things? I will test.. :) – jonalv Mar 13 '15 at 14:53
• Updated the example to reflect needed features that I didn't think of when designing it. – jonalv Mar 13 '15 at 15:03
• I see. I have now posted a new approach that rewrites some internals of the todo package instead. – Andrew Swann Mar 13 '15 at 15:28
• Very nice! I feel that only accepting and moving on is not thanks enough... This seems to be exactly what I was dreaming about! – jonalv Mar 13 '15 at 15:38
