Is there a reason that uflash doesn't preserve filenames? about uflash HOT 4 OPEN

Knock yourself out..! :-) The -k --keepname sounds like a good way to go. Please remember the checklist at the end of here: https://github.com/ntoll/uflash/blob/master/CONTRIBUTING.rst

(BTW.... micropython.hex is used simply because uflash usually saves directly onto the device rather than the local FS [nobody has ever considered anyone would want to pre-create/save hex files with uflash]).

When I first learned about the hex format I was quite surprised that standalone compiler/hexifier program didn't exist. I wanted to demonstrate the microbit at my local makerspace and wanted to be able to just drag and drop pre-hexified files onto the microbit. Uflash almost fit the bill except for not preserving the filename.
I've completed my edits. I'll submit a pull request.

Great stuff... thank you! Looking forward to getting your PR. :-)

I'll have a second pull request soon. I wanted to have multi-input support (*.py, etc.) and finally decided that the simplest way to implement that was to create a separate script (hexify.py) that loads uflash.py as a module. I've got it working but I'll need to add tests and documentation.
