Just a listing of stuff that I have built.

Joplin to Todost

Joplin to Todost is a free plug-in I wrote that allows you to create new Todoist tasks directly from inside a Joplin note. It creates a Todoist link in the Joplin note so you can jump to the Todist task directly from Joplin. It also add a Joplin note link in the Todoist task. Definitely worth checking out if you use Joplin and Todoist.
