Does ToDoist support URL schemes to it can Work with Drafts?
Unfortunately, we don't support URL schemes right now, but we will consider it in the future and you're welcome to vote for this request in the iOS Votebox: http://todoist.com/Vote_iOS/showProposal/45/
Too bad votebox is closed but I would like to second this suggestion. I'd love to have Drafts integration for Todoist.
Would love to be able to send tasks from Drafts to Todoist via URL Schemes.
Yes please. This would also allow Todoist to work with Airmail, at least according to their dev team.
