[FR] Row numbering, full-sized kb

[cogscides]

Thank you for this lib, I worked on pet project for Obsidian and wanted to create something like this. It helps me 🙏

Some feature requests, maybe you have some ideas on it:

1. row styling. At the current moment all rows have "row--0" style by some reason. So it's unpossible to change height manually for row

2. Maybe you have some ideas how can be implemented something like this full-sized kb? keyboard-layout-editor.com

At the moment I'm working on trying to make something like this full-sized kb with responsiveness.
