[BUG] No option for accessible settings change

Describe the bug With end of sale of Prusa I3 MK3S+, I think it's a high time to present serious accessibility issue regarding new firmware. In legacy Prusa-Firmware we had D-codes and M500 enabling blind users to change any printer setting. I just could find a corresponding EEPROM address in the code and that was all. With new Prusa-Firmware-Buddy I'm, as a blind person, unable to change basic settings. For example we spent some weeks ago over a hour on your Live Chat finding any way of storing Z-offset to EEPROM - no success. If Prusa MK4 is to be successor of Prusa I3 MK3S+, please don't make such accessibility regression. We don't specifically need return of D-codes, but any way to change printer settings via USB.

How to reproduce N/A

Expected behavior Any possibility of changing settings without access to the screen.

G-code N/A

Crash dump file N/A

Video N/A

I just thought to myself that we probably have a solution, in addition relatively simple to implement and also useful for other users during debug or configuring print farms. Since we can use a txt file to configure the network, we could expand this idea to export/import all settings from the printer. A simple gCode could be created that exports and imports settings from a txt file to a flash drive.

As this is no bug, please change the title to feature request. Thanks ;)

Hi @bkerler If you had an option to use your device and it disappeared in the next release, you'd consider it a bug. We had accessibility options in legacy firmware, and since MK3.5/MK4 are officially said as successors to MK3 series, I consider lack of possibility we had in previous model is a bug. :)

As @dawidpieper said, this is properly a regression, not a feature request.
