When you login to your LeadSimple account you will be automatically placed on the first pipeline that was created on the account.
You might want to have a different view when you login to your account (maybe a different pipeline, process type, or your tasks page); for that reason you now have the opportunity to select your default view.
All you need to do is go to your profile:
From there go to the drop-down menu that's called "Default Login Page" and select between Tasks, All Processes, an individual Pipeline, or Process you prefer.
