Hi zYx,
Can't answer the VFD stuff I'm afraid, but will try with some of the other stuff.
Quite easy to change the fonts, you will need to copy the font files over the /usr/share/enigma2/metrixhd/fonts and edit the beginning of the file skin.xml with the new font names. Let me know if it looks any good
VIX menu is fixed in the next update, and I'm aware that some of list's are obscured which will get fixed after the xmas period, however if you can be more specific I can make sure they're fixed quicker.
Thanks, Steve
