Michael Guterl's Preonic Layout
I have a very similar keymap for my Planck.
Check out my userspace for the custom keycodes that are used in keymap.c.
At a very high level I use 4 layers:
- Qwerty - Letters
- Util - Vimkeys for navigation and other convenient things
- Raise - Numbers and F keys
- Lower - Symbols
