You can filter the tasks using the different filters shown on the Tasks Page.
Filter the tasks based on the task source to Prospect field options.
You can even filter the tasks out based on their Priority.
As an Example there are tasks that are very critical and needs to be executed before all the other tasks.
While creating those tasks you have set their Priority as 'Critical' and you want to execute them the moment you log into the system.
In this case all you have to do is Click on the Priority Filter and Select the Priority as Critical, all the tasks that have the priority set as Critical will be shown and then you can start executing them.
