Would be cool to be able to set some permissions based on who is assigned to the particular record.
This would allow everyone in a solution to still be able to access some information on the record while keeping some information private to only admins and the person assigned to that record.
Case Study: We use formulas to determine the estimated budget for each task. Once an employee assigns themself to the task, another formula divides the budget by their individual pay per hour to give them an estimated amount of time on how long they have to complete the task.
While we have most of these fields hidden from anyone who isn't management, we would like to also hide the "estimated time" field from anyone who is not assigned to that part of the task.
That said, other aspects of the record should be viewed by other employees.
