Could you please elaborate on what a status means? Just Open/Complete? Are you using Alfresco Process Services (enterprise version) or Community Activiti?
Both in Community and Enterprise versions, there are task query APIs which let you query for all the tasks that you are involved in. If you are using the Enterprise version, you could use Application Development Framework to quickly build/customize your UI according to your needs.
I guess you're using the Activiti embedded in Alfresco Content repository as you mention Dashlet. You might be best to post a linked question under ECM (Alfresco Content Services (ECM) | Alfresco Community ) as if it's a Content-centred question you might get a quicker answer there. If it helps (and I think this is the Activiti bit) you can see an example of querying taskService for taskInvolvedUser on the thread
