Disable automatic display of columns/tables

[dudeman]

At times I have to connect to an Oracle database over satellite. When PL/SQL developer tries to autocomplete or display column names/table names automatically as I type in commands it really slows things down. Is there a way to turn that feature off?

Preferences -> User Interface -> Code Assistant.
Disable "Automatically activated".

Also, ypu may like to disable "Show dictionary info in result grid" in "SQL Window" group.
