I am not sure if this is the right place to post this.
In case this is useful to anyone else: For editing logseq pages, I am using obsidian with vimrc support plugin. There’s a key binding where [[ and ]] navigates markdown headings. I you change the regular expression it uses to /^[ \t]*(?:- )?#(#*) /gm then it works for logseq markdown also.
