*
* * `"both"` (the default) - The plugin is added to both grids
* * `"top"` - The plugin is added to the containing Panel
* * `"locked"` - The plugin is added to the locked (left) grid
* * `"normal"` - The plugin is added to the normal (right) grid
*
* If `both` is specified, then each copy of the plugin gains a property `lockingPartner` which references its sibling on the other side so that they
* can synchronize operations is necessary.
*
* {@link #features Features} may also be configured with `lockableScope` and may target the locked grid, the normal grid or both grids. Features
* also get a `lockingPartner` reference injected.
