Dactyl-ManuForm hybrid with opposing thumb clusters:
That looks quite cool and worth a check if you are interested in contoured keyboards and prefer to press thumb buttons in the horizontal direction. It has a smaller number of thumb keys. The required dexterity in the tip thumb segment (phalange with fingernail) for the nearest button seems to be about the same as for my macro key. Not bad.
Also a full keyboard configuration (layout/programs/macros/triggers) can be saved/loaded to/from a file using Katy's qtclient (KeyboardClient) now. And there was a fix of an intermittent bug in firmware when a macro redefinition led to macro storage corruption.
