keymap-editor VS zmk-helpers

The difference is: https://nickcoutsos.github.io/keymap-editor/ Click the firmware generated button which takes you directly to the action tab for the latest build. Then clicking to download firmware.

Looks nice. I can recommend the following graphical configurator: https://github.com/nickcoutsos/keymap-editor

I haven't looked into QMK configurators because if I go to the trouble of building a keeb I'd go all out and make it wireless. I did look at [keymap editor](https://github.com/nickcoutsos/keymap-editor) for ZMK, which could be close enough to Oryx for me to try sometime.

The only other thing I could recommend in that case is custom built; it's easier than you'd think, and some people have made GUI interfaces for ZMK like this: https://github.com/nickcoutsos/keymap-editor

I know ZMK does not have an official one, but there's one that uses github actions in order to build a firmware for you after you commit your keymap. That's probably the closest we'll have to zmk configurator for a while https://github.com/nickcoutsos/keymap-editor

I think the closest thing at the moment is https://github.com/nickcoutsos/keymap-editor.

Looking forwards: the chosen bootloader should support over-the-air updates, and GUI front-ends for ZMK do exist, albeit with varying maturity. 1 2

With ZMK, I followed the instruction from https://github.com/urob/zmk-nodefree-config.

Add zmk-nodefree-config to your repo to make key position definitions easier

A more advanced solution would be to output the Unicode character of em-dash (u+2014), you can easily do that with the zmk-node-tree-config by urob.

While I see that you already got help zmk-nodefree-config is pretty good as well.
