Support file-local variables

[johnhamelink]

I'd like to use a persistent-scratch buffer as a casual org-mode todo list, and I'd like to set a few local variables in that buffer that will load when the scratch buffer is loaded, but if I use add-file-local-variable to add these variables to the buffer, they don't seem to be evaluated when the buffer is filled.

I'd like to set up some minor modes (I note that persistent-scratch-what-to-save doesn't support minor modes), org-tag-alist, and org-archive-location.

Thanks :)
