Reach feature parity with Everdo

Everdo is another GTD app with a similar design to Nextool. We want to either copy or implement alternatives to all Everdo features. This is a list of features Everdo has that we don't:

• [ ] #4
• [ ] #6
• [ ] Inbox
• [ ] Deletion of tasks
• [ ] Tagging (filtering by tags, tags colors)
• [ ] Contexts (list of contexts in sidebar)
• [ ] Areas
• [ ] Search
• [ ] Notebooks
• [ ] Grouping items by type or project in view
• [ ] Time estimates (filtering by time estimates)
• [ ] Effort estimates (filtering by effort estimates)
• [ ] 'Waiting for' (tracking delegated tasks)
• [ ] Notes
• [ ] Repeating tasks
• [ ] Synchronization (low priority)
• [ ] Mobile app (low priority)
