# Flags

The `flags` option is used to toggle features on the config. Let's see an example of how to use the flags option to disable the Better Vim tabs feature:
Open your Better Vim config and add the `flags` option:

```lua better-vim.lua theme={null}
return {
  flags = {
    disable_tabs = true
  }
}
```

Reopen your **neovim** and you'll notice that there are no tabs on the top.

## Available flags

### `disable_tabs`

Disable the tabs feature.

* Options: `true` and `false`
* Default: `false`

### `format_on_save`

Auto format the code on save if the LSP has this feature.

* Options: `true` and `false`
* Default: `false`

### `disable_auto_theme_loading`

Disable theme auto loading. Use this flag if you want to setup your theme manually without setting `colorscheme` and loading themes automatically.

* Options: `true` and `false`
* Default: `false`

### `experimental_tsserver`

Use [`typescript-tools`](https://github.com/pmizio/typescript-tools.nvim) as LSP instead of `tsserver` from [`mason-lspconfig`](https://github.com/williamboman/mason-lspconfig.nvim).
This feature is experimental, but you can enable/disable it any time.
To create your own custom `on_attach` function, you can keep using `lsps.tsserver`, as shown in [Installing LSPs](/customization/installing-lsps) section.

* Options: `true` and `false`
* Default: `false`
