 NERDTree can be extended with custom mappings and functions using its built-in API. The details of this API are described in the included documentation.

 ### How can I close Vim or a tab automatically when NERDTree is the last window?
 
+Because of the changes in how Vim handles its `autocmd` and layout locking `quit` command is no longer available in Vim9 auto commands, Depending on which version you're running select one of these solutions.
