Hey, thank you for your appreciation!
So in the last public release it is already possible to export map binaries in bit-depths greater than 8...
- Import/Export >> Binary >> Export All (essentials, multiple files, configurable)
There you can select between 8, 12 or 16 bit and also between whole map, selected area and sub-maps.
Does this solve your request? or maybe you are wanting a single binary file containing lo,hi,lo,hi,lo,hi bytes etc
This is not yet available, having two arrays for the low, high bytes of 16-bit values seems to be the most commonly used way but there are definitely some further options that could be added to the current Import/Export system in future releases.
Cheers.
