Flip layers but keep thum keys

[Juanal07]

What's the best way to flip layers but keep esc, space, tab thumb keys to the right?

Is it worth to try to manual config miryoku with some customizations like moving the numpad 1 key or change the order of some symbols? or is better to just create my own zmk config file?

Is there some science related to symbols? at least for programming I fill like I can make better approaches to my needs like puting open/close symbols together.

I love the project and the work put into it, thanks!

I already answered myself looking at documentation :)
