To Do List/Checklist

To Do List/Checklist

Looking for a way to create a To Do List/Checklist in the CRM.  We have looked into the blueprint/pipeline option but as our "to dos" could happen in various stages, it doesn't work for us.  It might be an option if we could have more than 1 pipeline but apparently that's not an option right now. 

What is the easiest way to have a simple To Do List/Checklist?  We just want to have a list that we check off as completed. 

Thank you!
