Please redesign your portfolio database

Seriously, SA has excellent content, but whoever designed this should go back to school or avoid anything to do with database development. 

1) cannot delete symbols at the source, need to go to another screen, or in my case have multiple screens to do this.

2) unable to change title to portfolio.

3) have to input symbols instead of Excel download

4) Unable to move symbols easily from one portfolio to another.

5) Is anyone here aware of cut and paste, or is everything compartmentalized 

Sent email for #1, never had a response. How long has SA had a premium account? would the upgrade from cardboard to platinum aleviate the issues .
