 *** TODO gnuplot
 https://github.com/dpezto/tree-sitter-gnuplot is not on crates.io so I'd have to add a git dependency to use it. This would prevent publishing this crate to crates.io.
 ** DONE Bug: carry over highlight starts when breaking lines
+** TODO Add dates to posts
+** DONE Add support for unlisted posts (posts that do not show up on the homepage).
+** TODO Add support for showing file name where we currently show language
