we have so many tasks that often it is difficult if not impossible to locate a task using current filters.
it would be enormously helpful to be able to show all @ mentions of a specified user and all comments by a user, sorted by date.
eg. i know i had asked jill a question using @jill but cannot locate the task. filtering all @jill and sorted by date would let me find this quickly
eg. i know that john had said something about x y and z but cannot find the task where he said that. filtering all comments by john, looking at the most recent, would help me find this
