Nearly two weeks after starting the +OneNote
experiment, I'm more than happy to say that it works like a charm.
I admit there is no overview board, but being able to drag & drop mails from Outlook directly into pages and creating Outlook tasks from pages is simply awesome.
Put everything you need for a task together and sync it all. Awesome.
The perfect solution would be to have some sort of Kanban overview for all tasks and link each of them with a OneNote page, thus moving the organisation part from OneNote to Outlook.
