I run my business solo and have no intention of getting my family involved in my insanity and I'm sure there are at least a few other solo businesses out there :P So a plan based on the needs of the solo entrepreneur is required. This would not include any team collaboration features but would have; projects, subtasks (with due dates cause subtasks are just notes without a due date), attachments to upload docs, pictures, pdfs, advanced customisations for recurring tasks and integration with a Calendar and a Note app. Currently, I would still need Evernote to hold my extensive project notes.
