It would be a nice improvement if links which are on a to-do rem are deleted upon completion.
E.g. I have a to do rem which says "Reorganize notes " and the notes links to a particular rem in another document. Once I have finished reorganizing the notes, I mark the rem as done, but when I open the document I have linked to, the link for the to-do is still there. I can see this being an issue if you have a to-do for the same document multiple times.
Being able to remove links once the to-do is completed could make it more clean
