Feature Request: Navigation & Task Visibility Improvements

The customer, David, reports that the core Akiflow workflow, including Inbox, tags, flags, and folders, is working perfectly. However, he finds the current navigation and task visibility confusing, expressing a fear of missing important tasks. Key feedback points include: - Request for a 'Done' section to be added to the left navigation. - The 'Upcoming,' 'Today,' and 'All Tasks' views are unclear, with tasks appearing in various sections (e.g., 'Week' within 'Today,' or 'view all planned tasks' within 'Upcoming'). - Suggests displaying all planned tasks in a single column, divided by headlines, for improved organization. - Notes that the floating bar on the right side hides or contains other items, contributing to the confusion. The customer is seeking improvements in future updates to address these UI and navigation concerns.
