When using an Oracle data source, databases may contain a large number of tables. ModelBuilder currently loads all tables with their checkboxes selected by default, forcing users to uncheck them one by one. To improve usability, the tables could be loaded unchecked by default, or ModelBuilder could include an "Uncheck All Tables" option. This option could be added to the "Choose the tables you would like to work with:" section, which currently only contains the Duplicate and Remove options.
