I’m a complete n00b here, but I have been tinkering with my Daily Notes Templater err… template and hadn’t really thought of this as an issue until you mentioned it… Thanks! 
There may be a much more elegant way to accomplish this, but after a little experimentation, I replaced my “Yesterday / Tomorrow” equivalent to your example with this, culled from the concepts in Bryan Jenks’ Templater Control/Flow published note (Thanks @tallguyjenks!).
<%* if (tp.date.now("ddd", 0, tp.file.title, "YYYY-MM-DD") == "Mon") { %>[Last Friday](<% tp.date.now("YYYY-MM-DD", -3, tp.file.title, "YYYY-MM-DD") %>) <%* } else { %>[Yesterday](<% tp.date.now("YYYY-MM-DD", -1, tp.file.title, "YYYY-MM-DD") %>) <%* } %> / <%* if (tp.date.now("ddd", 0, tp.file.title, "YYYY-MM-DD") == "Fri") { %>[Next Monday](<% tp.date.now("YYYY-MM-DD", 3, tp.file.title, "YYYY-MM-DD") %>) <%* } else { %>[Tomorrow](<% tp.date.now("YYYY-MM-DD", 1, tp.file.title, "YYYY-MM-DD") %>) <%* } %>
I’ve left it as a long single line as I’m not 100% sure if I tried to arrange it into more readable templated Javascript that I’d get all the important syntax in the right places. It’s basically a pair of if/else statements that say if this note is for a Monday, “Yesterday” becomes “Last Friday” and today-3 on the link and, if today is Friday, “Tomorrow” becomes “Next Monday” and today+3 on the link.
When I have more time I might have a think about what to do if I do create a daily note at the weekend, which might be as simple as not inserting those links at all…
PS. can anyone tell me how to insert a code-block into a post? Both pre-formatted and block quote still messed with my layout when I tried to post the multiline code.
