Would love to see the option to check boxes next to tasks in the 'Open Task Activity' related list within a module record (not just in the "Task Activity" module) to be able to mass-update or mass-delete. It is quite painful when you need to delete tasks that are future dated to have to search for them in the Task Activity model - merely because often times in modern browsers it seems that going into an individual task and and click 'delete' never brings up the confirmation box to delete it that way.
