Layout proposal similar to Qt Virtual Keyboard

[itsprdsw]

Hello everyone,
First of all thank you for the great work done with this plugin.
In the development that I am doing and starting from the base that you have proposed with this plugin, I have customized the style of all the layouts so that it is as similar as possible to the official Qt one.
You can see this development in this fork https://github.com/itsprdsw/cutekeyboard/tree/customization
If you think it could be interesting to include it in the main branch of the project, I would be happy to contribute to it.
Thank you and greetings.
