Virtual Keyboard

I'm really surprised which nice design this virtual keyboard has!

It comes straight from Qwen3-Coder-480B-A35B-Instruct!! :-o

... I will integrate it into my design, l8rs.
The current code is changed and extended by me and myself. ...

Update [2025-08-28]: I've just integrated many nice extensions ...and I hope there are 'no'(...) bugs left..

In case you find some, please call me. :-)
