Main features of «Keyboard Layout Indicator» you can see on video

Added Added the ability to change RGB Lighting of keyboards. Keyboard Lighting can change color depending on the keyboard layout. Currently supported RGB keyboards from LOGITECH (Logitech G213, Logitech G413, Logitech G512, Logitech G513, Logitech G813, Logitech G913, Logitech G Pro and others...) that work with Logitech G-HUB.

Before use, you must install the Logitech G-HUB Software from official web site:

https://www.logitechg.com/en-us/innovation/g-hub.html

Added the ability to change the backlight of any RGB devices (depending on the keyboard layout and the state of the NumLock/CapsLock keys), using a bundle with the OpenRGB program. OpenRGB is free software that provides control of various RGB devices and provides an open SDK for controlling RGB devices from any programs, which is used in Keyboard Layout Indicator.

Now you can change the color of the keyboard (if it has RGB control), the color of the workplace lighting (by connecting an RGB LED strip to the connector on the motherboard), the color of the RGB mouse pad or the color of the RGB audio speaker depending on the current layout.

A complete list of all supported RGB devices can be found on the official website of the OpenRGB project:
https://openrgb.org/devices.html

You need to download and install the software "OpenRGB" from the official website, and run the SDK Server by simply clicking the appropriate button. After a while, "Keyboard Layout Indicator" will connect to it, this will be visible in the list of connected clients (as in the screenshot). After that, backlight control will become available, i.e. "Keyboard Layout Indicator" -> "OpenRGB" -> RGB Keyboard

In the program, you need to set the address and port of this OpenRGB SDK server (you can leave it as is by default if you did not change it in the OpenRGB settings) and the desired colors for specific backlight zones. You can set backlight colors for both keyboard layouts and for the state of the NumLock/CapsLock keys, for any zones available on a specific device.
