The TOTEM was my first experience with ergomechs and I've been loving it, such a compact little board but doesn't sacrifice too many keys for functionality.

I've also quite liked the increased pinky stagger and splay, but that stuff comes down to personal preference/resting hand shape. The tiny Seeed Xiao controllers are nice too, almost wish I had a spare one to tinker with but I set up my board with a dongle instead of true Bluetooth to save some battery and make it more portable, so the extra microcontroller got put to use. I think I've gotten over 2 months of regular use on a single charge with the dongle setup, so I'd say it was worth it.

Here's a visual representation :)

A lot of combos, basically.

There is an example of config in the keyboard's repo. https://github.com/kilipan/teenspirit
