# Custom Bars

Custom Bars can be displayed within the EmEditor window. With this feature, useful plug-ins such as Outlining, Web Preview, and Search Bar can be developed. Many features were added to support outlining and custom bars.

- Explorer Plug-in

- Open Documents Plug-in

- Search Plug-in

- Snippets Plug-in
