This is absolutely a nice-to-have and low on the list. It's just a bit more elegant and accessible than the usual.

Given the way we get themes running through multiple posts, accumulate information across multiple posts, and return to topics, it would be nice to have an quick way to cross-link to another post. Something like typing [[o to bring up a drop-down menu of the most recent posts on Ovarit, [[o/ to get the local circle, and [[s: to search for a word in the title or text.
