# GOCUI - Go Console User Interface
|
|
|
|
[](https://godoc.org/github.com/jroimartin/gocui)
|
|
|
|

## Features

|
|

|
|
* Support for overlapping views.
|
|
* The GUI can be modified at runtime (concurrent-safe).
|
|
* Global and view-level keybindings.
|
|
* Mouse support.
|
|
* Customizable edition mode.
