Thanks a lot for your helpful messages! I will update my scripts ASAP!

Although I may remove the screen inversion button then, it was pretty much broken anyway (well it was working, but it was a dirty hack). I will leave it as a configuration parameter nonetheless.
As for the font, thanks for the help, but my main issue was a FBInk bug, which you fixed in the last updates

I installed the last version and it now works fine.
Unrelated : Did you actually read all the code? These were tiny details I thought nobody would notice
