That’s a great method - I forgot about the built in share extensions.
And I’ve figured out a workaround for what I was thinking of - because you can create a calendar of Todoist tasks, they can actually appear as calendar events in Agenda, and can then associate notes with them.
At the end of the day, it maybe isn’t worth having task notes in Agenda rather than Todoist, but I like the way notes are presented in Agenda, as opposed ot the pop up box in Todoist.
Maybe my ideal would be for Todoist to have task notes in a third column rather than a pop up box. A bit like email programmes, with a column for folders (projects), a column for emails titles (tasks) and a column for currently selected email (notes for currently selected task).
Everyone’s workflow and preferences are different. But for me, it looks as though Agenda makes more sense than Evernote with how it works. So in conjunction with a calendar / Todoist and Toggl it will still be extremely useful. I just need to play around a bit and figure out what role I need each to play where there is a bit of overlap.
