Very nice, thanks for your work! For me this finally makes it possible to build my own note-orders on note-level and therefore helps to use Joplin as a Zettelkasten. (What would make a good zettelkasten plugin?) Especially the "Deep-Backlinks" with the highlighting after the jump into the link-source is very usefull.
Only downside for me so far: quicklink doesn't work with spaces in between the query, as the original quicklink plugin does. Also i can't get the original quicklink plugin to work again, although i disabled the feature in the new plugin.
