I would love a catch all "Activity" tab for each client & project. The client screen would show all activity on the client screen, including changes to the client record as well as all activity across all projects related to the client - effectively, the project "activity tab" rolled up. The project activity tab would just show activity specific to that project. Activity would cover everything: timesheets, notes, tasks & subtasks, comments, agreements, invoices, emails etc... Just a simple date and time based list with a title, category and important info as relevant (eg: time logged for timesheets or invoice amount for invoice). I would love if it was searchable by keyword, category and date to make it easier to locate information. I find myself not using comments as much as I would like and adding notes both in the project and client screens because I struggle to find relevant information retrospectively and end up digging through archived tasks and projects which is time consuming. Activity tabs per client & project would be incredibly powerful and would help me use the tool far more efficiently.
