The base context menu offers a selection of swift actions that can be executed on a base. To access this menu, click on the ellipsis symbol (`...`) located adjacent to the base name within the left sidebar.
If you determine that a base is no longer necessary, you have the option to permanently remove it from your workspace. Deleting a base will delete all the tables and data associated with it.
Some general configurations are available for you to modify within the base settings.
1.**Show M2M tables**: Toggle this option to display/hide M2M tables within the left sidebar. Many-to-many relation is supported via a junction table & is hidden by default.
2.**Show NULL in cells**: Toggle this option to display/hide NULL values within the cells of the table. This helps differentiate against cells holding EMPTY string.
3.**Show NULL & Empty in Filters**: Enable 'additional' filters to differentiate fields containing NULL & Empty Strings. Default support for Blank treats both NULL & Empty strings alike.
To configure base settings, you can follow these steps:
1. Initiate the base context menu by clicking on the ellipses `...` located next to the base name within the left sidebar.
2. In the dropdown menu that appears, choose the `Rename` option.
